Ted Yu created MAPREDUCE-5819:
---------------------------------
Summary: Binary token merge should be done once in
TokenCache#obtainTokensForNamenodesInternal()
Key: MAPREDUCE-5819
URL: https://issues.apache.org/jira/browse/MAPREDUCE-5819
Project: Hadoop Map/Reduce
Issue Type: Improvement
Reporter: Ted Yu
Assignee: Ted Yu
Priority: Minor
Currently mergeBinaryTokens() is called by every invocation of
obtainTokensForNamenodesInternal(FileSystem, Credentials, Configuration) in the
loop of obtainTokensForNamenodesInternal(Credentials, Path[], Configuration).
This can be simplified so that mergeBinaryTokens() is called only once in
obtainTokensForNamenodesInternal(Credentials, Path[], Configuration).
