Ted Yu commented on HBASE-7070:
-------------------------------
2 * CLIENT_RETRIES_NUMBER appears twice in the patch, consider introducing a
constant for it.
{code}
+ assertTrue("Expected try number=" + CLIENT_RETRIES_NUMBER + ", actual ="
+ + RegionServerWithScanTimeout.tryNumber,
+ RegionServerWithScanTimeout.tryNumber <= 2 * CLIENT_RETRIES_NUMBER);
{code}
Expected try number is 2 * CLIENT_RETRIES_NUMBER, not CLIENT_RETRIES_NUMBER.
{code}
+ } catch (IOException ioe) {
+ // catch the exception after max retry number
{code}
Add a log in the catch block ?
> Scanner may retry forever after HBASE-5974
