Machine Learning Part 5

By Dinesh
In this blog, we will describe another example that utilize KMeans & Spark to determine locations.

Before that, we would suggest you to got to previous blogs -

In this blog, we will analyze and try to make predictions on Fire detection GIS Data- https://fsapps.nwcg.gov/gisdata.php

  1. We will have historical data of Wild fires.
  2. And, we will try to analyze. That is eventually helpful to reduce response time in case of fire, reduce cost, reduce damages due to fire, etc.
Fire can grow exponentially based on various factors like - Wild life, Wind Velocity, terrain surface, etc. Incident tackle time is limited by various factors one of which is moving firefighting equipment. If we are plan in advance where to place equipment's such that it is close to a fire prone area. It is possible to reduce response time.

So, we can analyze the historical data and try to group them in a cluster, which has a centroid. This centroid can be helpful to determine location to make water tanks, keep fire equipment's, etc. As, this location will be close to the locations where fire has affected in past. 

K-Means is a clustering algorithm that fits suitable in this scenario and we will try to use the same.

Mostly, what we have seen a simplistic singular pipeline. But, we can have a pipeline implemented as per Rendezvous Architecture, where-in, multiple models can be applied to an request, and a user defined logic can be applied to return the best fit results to requester.  For example, We might want to locate a correct GPS address for some grocery store, or in case of Fire: we may require to alert a Fire site which can reach the location quickly, rather than the location which is close to Fire. So, an incoming request may be required to optimize with different models for different objectives. Like - Speed vs Accuracy.

We will discuss more about Rendezvous Architecture in future blogs.

This example is pretty much same as what we have seen in previous blog. But, Refer - @ https://github.com/dinesh028/SparkDS/tree/master/src/indore/dinesh/sachdev/forestfire/

Read from a hive table and write back to it using spark sql

By Dinesh
In context to Spark 2.2 - if we read from an hive table and write to same, we get following exception- scala > dy . write . mode ( "overwrite" ). insertInto ( "incremental.test2" ) org . apache . spark . sql . AnalysisException : Cannot insert overwrite into table that is also being read from .; org . apache . spark . sql . AnalysisException : Cannot insert overwrite into table that is also being read from .; 1. This error means that our process is reading from same table and writing to same table. 2. Normally, this should work as process writes to directory .hiveStaging... 3. This error occurs in case of saveAsTable method, as it overwrites entire table instead of individual partitions. 4. This error should not occur with insertInto method, as it overwrites partitions not the table. 5. A reason why this happening is because Hive table has following Spark TBLProperties in its definition. This problem will solve for insertInto met

Hive Parse JSON with Array Columns and Explode it in to Multiple rows.

By Dinesh
 Say we have a JSON String like below -  { "billingCountry":"US" "orderItems":[       {          "itemId":1,          "product":"D1"       },   {          "itemId":2,          "product":"D2"       }    ] } And, our aim is to get output parsed like below -  itemId product 1 D1 2 D2   First, We can parse JSON as follows to get JSON String get_json_object(value, '$.orderItems.itemId') as itemId get_json_object(value, '$.orderItems.product') as product Second, Above will result String value like "[1,2]". We want to convert it to Array as follows - split(regexp_extract(get_json_object(value, '$.orderItems.itemId'),'^\\["(.*)\\"]$',1),'","') as itemId split(regexp_extract(get_json_object(value, '$.orderItems.product'),'^\\["(.*)\\"]$',1),&

Caused by: java.lang.UnsupportedOperationException: org.apache.parquet.column.values.dictionary.PlainValuesDictionary$PlainIntegerDictionary

By Dinesh
Exception -  Caused by: java.lang.UnsupportedOperationException: org.apache.parquet.column.values.dictionary.PlainValuesDictionary$PlainIntegerDictionary at org.apache.parquet.column.Dictionary.decodeToBinary(Dictionary.java:44) at org.apache.spark.sql.execution.vectorized.ColumnVector.getUTF8String(ColumnVector.java:645) at org.apache.spark.sql.catalyst.expressions.GeneratedClass$GeneratedIterator.processNext(Unknown Source) Analysis - This might occur because of data type mismatch between Hive Table & written Parquet file. Solution - Correct the data type to match between Hive Table & Parquet

Hadoop Distcp Error Duplicate files in input path

By Dinesh
  One may face following error while copying data from one cluster to other, using Distcp  Command: hadoop distcp -i {src} {tgt} Error: org.apache.hadoop.toolsCopyListing$DulicateFileException: File would cause duplicates. Ideally there can't be same file names. So, what might be happening in your case is you trying to copy partitioned table from one cluster to other. And, 2 different named partitions have same file name. Your solution is to correct Source path  {src}  in your command, such that you provide path uptil partitioned sub directory, not the file. For ex - Refer below : /a/partcol=1/file1.txt /a/partcol=2/file1.txt If you use  {src}  as  "/a/*/*"  then you will get the error  "File would cause duplicates." But, if you use  {src}  as  "/a"  then you will not get error in copying.
