Anoop Sam John commented on HBASE-15325: ---------------------------------------- [~yangzhe1991] U will provide new patch with client side only change? As noted in RB {quote} I fear we can not do this. Checking where all we use this, at server side usage area, seems we have to have this change. eg: Filter#reset() should be called btw rows not btw batches. So batch limit check addition seems correct there. {quote} So this is another issue related to Filter when batched read in place. We can track it as another issue? Will raise? > ResultScanner allowing partial result will miss the rest of the row if the > region is moved between two rpc requests > ------------------------------------------------------------------------------------------------------------------- > > Key: HBASE-15325 > URL: https://issues.apache.org/jira/browse/HBASE-15325 > Project: HBase > Issue Type: Bug > Components: dataloss, Scanners > Affects Versions: 1.2.0, 1.1.3 > Reporter: Phil Yang > Assignee: Phil Yang > Priority: Critical > Attachments: 15325-test.txt, HBASE-15325-v1.txt, HBASE-15325-v2.txt, > HBASE-15325-v3.txt, HBASE-15325-v5.txt, HBASE-15325-v6.1.txt, > HBASE-15325-v6.2.txt, HBASE-15325-v6.3.txt, HBASE-15325-v6.4.txt, > HBASE-15325-v6.5.txt, HBASE-15325-v6.txt > > > HBASE-11544 allow scan rpc return partial of a row to reduce memory usage for > one rpc request. And client can setAllowPartial or setBatch to get several > cells in a row instead of the whole row. > However, the status of the scanner is saved on server and we need this to get > the next part if there is a partial result before. If we move the region to > another RS, client will get a NotServingRegionException and open a new > scanner to the new RS which will be regarded as a new scan from the end of > this row. So the rest cells of the row of last result will be missing. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
