Tsz Wo (Nicholas), SZE commented on HDFS-3667:
----------------------------------------------
> HftpFileSystem.java no change in branch-1?
Yes. It is because HftpFileSystem does not use ByteRangeInputStream in
branch-1, i.e. it does not support seek.
> Runner#shouldRetry() has different code. Is it due to difference between
> branch-1 and trunk?
Yes. In trunk, the RPC retry policy was changed by the HA work.
> {{ conn.setRequestProperty("Content-Type", "application/octet-stream");}} is
> not set in branch-1 patch?
No, we have the following
{code}
//WebHdfsFileSystem.Runner.twoStepWrite()
conn.setRequestProperty("Content-Type",
MediaType.APPLICATION_OCTET_STREAM);
{code}
> Add retry support to WebHdfsFileSystem

> DFSClient (i.e. DistributedFileSystem) has a configurable retry policy and it
> retries on exceptions such as connection failure, safemode.
> WebHdfsFileSystem should have similar retry support.
