-------------------------------
Summary: FsDelegationToken should cache Token
Key: HBASE-24403
URL: https://issues.apache.org/jira/browse/HBASE-24403
Project: HBase
Issue Type: Bug
Reporter: wuchang
When doing Bulkload, we find that FsDelegationToken will acquire token of
NameNode everytime for a single file, although, from the comment ofÂ
acquireDelegationToken(), it claims that it is trying to find token in cache
firstly, but the newly requested token is never put to cache and thus the cache
is always empty;
In cases there are many files to do the bulk load, the token request will cause
big short to NameNode.
