Hudson commented on HBASE-16626: -------------------------------- FAILURE: Integrated in Jenkins build HBase-Trunk_matrix #1606 (See [https://builds.apache.org/job/HBase-Trunk_matrix/1606/]) HBASE-16626 User customized RegionScanner from 1.X is incompatible with (anoopsamjohn: rev 56be3ac7c8d203710f844cd799f2fa3496f0515a) * (edit) hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/RegionScanner.java > User customized RegionScanner from 1.X is incompatible with 2.0.0's off-heap > part > --------------------------------------------------------------------------------- > > Key: HBASE-16626 > URL: https://issues.apache.org/jira/browse/HBASE-16626 > Project: HBase > Issue Type: Sub-task > Components: Offheaping > Affects Versions: 2.0.0 > Reporter: Charlie Qiangeng Xu > Assignee: Charlie Qiangeng Xu > Fix For: 2.0.0 > > Attachments: HBASE-16626-v1.patch > > > Introduced by 2.0.0's off-heap feature, the interface RegionScanner extends a > new interface Shipper which contains a "shipped()" method. > In our case, some application user defined customized scanner that implements > Interface RegionScanner in 1.X . > After we back ported the Off Heap feature of 2.0.0, > RegionScannerShippedCallBack throws a "java.lang.AbstractMethodError" when > executing scanner.shipped(). It is because the customized scanner didn't > override the shipped method yet. > Instead of forcing every user to add a empty implementation(if they don't > really need to scan the file or the RS don't use L2 cache, they don't need to > do anything in shipped method) , adding a default method of shipped in > Interface RegionScanner might be a better way. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
