> On some Hadoop version, we keep getting "lease recovery" message at the time we check for scratchdir by opening for appending:
> {code}
> Failed to APPEND_FILE xxx for DFSClient_NONMAPREDUCE_785768631_1 on 10.0.0.18 because lease recovery is in progress. Try again later.

> java.io.IOException: Failed to replace a bad datanode on the existing pipeline due to no more good datanodes being available to try. (Nodes: current=[DatanodeInfoWithStorage[10.0.0.12:30010,DS-b355ac2a-a23a-418a-af9b-4c1b4e26afe8,DISK]], original=[DatanodeInfoWithStorage[10.0.0.12:30010,DS-b355ac2a-a23a-418a-af9b-4c1b4e26afe8,DISK]]). The current failed datanode replacement policy is DEFAULT, and a client may configure this via 'dfs.client.block.write.replace-datanode-on-failure.policy' in its configuration.

> The reason is not clear. However, if we remove hsync from SessionState, everything works as expected. Attach patch to remove hsync call for now.
