hadoop - ERROR 2245: Cannot get schema from loadFunc org.apache.hive.hcatalog.pig.HCatLoader -

-

i try load files partitioned hive table.

lkr_bu = load 'basename.tablename' using org.apache.hive.hcatalog.pig.hcatloader();

after running following error:

2016-07-04 15:01:58,743 [uber-subtaskrunner] error org.apache.pig.tools.grunt.grunt  - error 2245: cannot schema loadfunc org.apache.hive.hcatalog.pig.hcatloader

for information, have required libraries , hcatalog {loader, storer} works oozie launcher.

someone encountered kind of problem ?

there many steps need follow make hcatalog work in pig.

overall, assume have configured paths (hcatalog) , have included required jars in classpath.

if not, please follow post :- http://www.thecloudavenue.com/2013/11/installingandconfiguringhcatalogandintegratingwithpig.html#comment-form

or, can follow below post :- https://acadgild.com/blog/loading-and-storing-hive-data-into-pig/

after have followed steps above, need start following services :-

  • hiveserver2 --> hive --service hiveserver2
  • hive metastore --> hive --service metastore

after following above steps, work facing same issue , resolved it.

hope helps.
