Subject Re: How to execute pig script from java
Date Fri, 10 Aug 2018 20:36:42 GMT
Pig does not have any server. The client directly launches jobs on the YARN
cluster. You can just use the APIs in
http://pig.apache.org/docs/r0.17.0/api/org/apache/pig/PigServer.html to
execute scripts from your java program.
