---------------------------------
Summary: Add note about the limitations when running WAL against
higher version of hadoop
Key: HBASE-20841
URL: https://issues.apache.org/jira/browse/HBASE-20841
Project: HBase
Issue Type: Sub-task
Reporter: Duo Zhang
AsyncFSWAL may easily be broken when upgrading the DFSClient, so we introduced
a fallback logic in HBASE-20839. And also, WAL can not be written into a
directory with EC enabled, but the API for creating a non-EC file in EC
directory is not available in hadoop-2.8-, see HBASE-19369 for more details.
