Work Description: smarthanwang opened a new pull request #3909:
URL: https://github.com/apache/hadoop/pull/3909
JIRA https://issues.apache.org/jira/browse/HDFS-16431
### Description of PR
The context of CallerContext would be truncated when it exceeds the
maximum allowed length in server side. I think it's better to do check and
truncate in client side to reduce the unnecessary overhead of network and
memory for NN.
### How was this patch tested?
Add some UTs to test the context would be truncated correctly .
### For code changes:
1. Refactor CallerContext.Builder constrctor to simplify usage
2. Do context truncate before CallerContext.Builder.build()
