While running Pig scripts via Oozie, you might face SASL exception (even though Kerberos might be disabled).
To resolve same, just comment out following lines in hive-site.xml then upload it to “oozie.wf.application.path”, which were –
<!--property>
<name>hive.metastore.kerberos.keytab.file</name>
<value>/etc/security/keytabs/hive.service.keytab</value>
</property>
<property>
<name>hive.metastore.kerberos.principal</name>
<value>hive/_HOST@EXAMPLE.COM</value>
</property-->
