[jira] [Commented] (HADOOP-15860) ABFS: Trailing period in file names gets ignored for some operations.

Sean Mackrory commented on HADOOP-15860:
----------------------------------------

Should be trivial to write a test that reproduces this, but for some reason integration tests aren't running for me anymore. Will need to debug my config...

However after tracing this through, I strongly suspect the period is going missing server-side. CC'ing [~tmarquardt], [~DanielZhou]. The period stays with the write request as far as I can trace it, and seems to immediately be missing from any list request. Can easily be reproduced as follows:

{code}
hadoop fs -mkdir ${ABFS_ROOT}/test.
hadoop fs -ls ${ABFS_ROOT}/ # test. will be missing, but test will be present
{code}

> If you create a directory with a trailing period (e.g. '/test.') the period is silently dropped, and will be listed as simply '/test'. '/test.test' appears to work just fine.
