Pig: ERROR 1070: Could not resolve org.apache.hcatalog.pig.HCatLoader - [Solved] - CDH 5.4.X+
Hi All;
With new CDH versions class name for HCatalog loader changed. Unfortunately this is not documented clearly.
Just change
org.apache.hcatalog.pig.HCatLoader to org.apache.hive.hcatalog.pig.HCatLoader
in your pig scripts to solve problem.
I hope, you wont waste too much time like me.
PS: You still need to specify hive-site.xml
