Rohini Palaniswamy commented on PIG-5460:
-----------------------------------------
Change should just be
{code:java}
String tokenFile = System.getenv("HADOOP_TOKEN_FILE_LOCATION")
if(tokenFile != null && globalConf.get(MRConfiguration.JOB_CREDENTIALS_BINARY)
== null) {
globalConf.set(MRConfiguration.JOB_CREDENTIALS_BINARY, tokenFile);
globalConf.set("tez.credentials.path", tokenFile);
}
{code}
SecurityHelper.populateTokenCache will take care of reading from that. It would
be even better if you can put the above into a
configureCredentialFile(Configuration conf) method in SecurityHelper instead of
TezDAGBuilder and just call it from there, so that all related code is in one
place.
