Kihwal Lee commented on HDFS-6763:
----------------------------------
The checkstyle warning is about the file length.
{noformat}
FSNamesystem.java:1: File length is 7,301 lines (max allowed is 2,000)
{noformat}
The failed test cases pass 100% of times when run locally multiple times. The
failures seem indicate issues with the environment.
{noformat}
java.io.IOException: Unable to load OAuth2 connection factory
and
java.lang.NoClassDefFoundError: org/apache/hadoop/fs/XAttr$Builder
{noformat}

> quotas for the entire namespace. A standby NN using shared edits calls this
