---------------------------------
Summary: Do not Rethrow DoNotRetryIOException as
UnknownScannerException
Key: HBASE-17587
URL: https://issues.apache.org/jira/browse/HBASE-17587
Project: HBase
Issue Type: Bug
Components: Coprocessors, regionserver, rpc
Affects Versions: 2.0.0, 1.3.0
Reporter: Zach York
Assignee: Zach York
Fix For: 2.0.0, 1.4.0, 1.3.1
HBase commit
https://github.com/apache/hbase/commit/94ade6a514e9935a8c283befb31f29cd8d3a2045
broke co-processors (such as Phoenix) throwing DoNotRetryIOExceptions when
scanning a table. This change rethrows them as UnknownScannerExceptions which
the HBase client will retry on. This is unintended behavior since co-processors
should be able to throw DoNotRetryIOExceptions back to the client. This came up
through a phoenix IT when trying to upgrade to HBase 1.3.0
