org.apache.hadoop.hdfs.testPipelineRecoveryOnRestartFailure failed with the stack like:

{code}
After tracing the root cause, this bug was introduced by [HDFS-16534|https://issues.apache.org/jira/browse/HDFS-16534]. Because the block GS of client may be smaller than DN when pipeline recovery failed.
