-------------------------------
Summary: StorageException complaining " no lease ID" during HBase
distributed log splitting
Key: HADOOP-11685
URL: https://issues.apache.org/jira/browse/HADOOP-11685
Project: Hadoop Common
Issue Type: Bug
Components: tools
Reporter: Duo Xu
Assignee: Duo Xu
This is similar to HADOOP-11523, but in a different place. During HBase
distributed log splitting, multiple threads will access the same folder called
"recovered.edits". However, lots of places in our WASB code did not acquire
lease and simply passed null to Azure storage, which caused this issue.

The fix is simple, just to acquire lease before the operation mkdir. However,
this might hurt performance a little bit, I will locally run a perf test before
submitting the patch.
