------------------------------------
Summary: Handling of DeserializationException causes needless
retry on failure
Key: HBASE-12334
URL: https://issues.apache.org/jira/browse/HBASE-12334
Project: HBase
Issue Type: Bug
Affects Versions: 0.98.7
Reporter: James Taylor
If an unexpected exception occurs when deserialization occurs for a custom
filter, the exception gets wrapped in a DeserializationException. Since this
exception is in turn wrapped in an IOException, the many loop retry logic kicks
in. The net effect is that this same deserialization error occurs again and
again as the retries occur, just causing the client to wait needlessly.
IMO, either the parseFrom methods should be allowed to throw whatever type of
IOException they'd like, in which case they could throw a
DoNotRetryIOException, or a DeserializationException should be wrapped in a
DoNotRetryIOException.
