Hello Jagannath,

Below exception will come when pigclient not able find the hdfs conf= iguraions..you need to do following..     


Set the PIG_CLASSPATH environment variable to the location of the cluster c= onfiguration directory (the directory that contains the core-site.xml, hdfs= -site.xml and mapred-site.xml files): 
  1. export PIG_CLASSPATH=
=3D/mycluster/conf=0A=
  2. Set the HADOOP_CONF_DIR environment variable to the location of the cluster= configuration directory: 
    export HADOOP_CONF_D=
IR=3D/mycluster/conf




Thanks & Regards

Brahma Reddy Battula
