Subject [jira] [Created] (HBASE-17587) Do not Rethrow DoNotRetryIOException as UnknownScannerException
Date Thu, 02 Feb 2017 20:50:51 GMT
Zach York created HBASE-17587:

             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
