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)
