[jira] [Commented] (HBASE-10181) HBaseObjectWritable.readObject
catches DoNotRetryIOException and wraps it back in a regular IOException

> Key: HBASE-10181
> URL: https://issues.apache.org/jira/browse/HBASE-10181
> Project: HBase
> Issue Type: Bug
> Components: IPC/RPC
> Affects Versions: 0.94.12
> Reporter: Samarth
>
> Exception handling inside HbaseObjectWritable needs to be reworked, IMHO.
> For example:
> At several places inside HbaseObjectWritable.readObject, exceptions are caught and rethrown as I/O Exception (including ClassNotFoundException!).
> So, if an implementation of readFields method throws a DoNotRetryIOException, HBase still ends up retrying.
> This problem exists at least in 0.94.12 version of HBase.
