Description

HBase rest scan may result incomplete data when https://issues.apache.org/jira/browse/HBASE-14533 or any other unexpected IOException happened in hbase rest service;

in ScannerResultGenerator.java @line 181

 

catch (IOException e) {
    LOG.error(StringUtils.stringifyException(e));
}

when RetriesExhaustedException thrown, it just eat the exception and scan complete without any error from client side view, which result severe business impact.
