ramkrishna.s.vasudevan commented on HBASE-16604:
bq.Thus, ClientScanner will re-open a new RegionScanner by sending a new scan
request and get a new scanner name.
Let me check this. I was wrong may be.
bq.The heap will be reset correctly, because the region scanner is closed for
good. A completely new RegionScanner will be constructed from scratch.
Ok.
bq.Is it the case that if the scanner is already closed, shipped() will not
free up the blocks?
The problem here is that the finally block will reset the rpcCallBack with the
RpcShippedCallBack and since the lease is already removed we don't add back the
lease and so the LeaseExpiry logic does not work which actually does the return
of the blocks. Anyway I think I have a better logic now to fix this after
seeing your comments. Will be back here.
bq.Yes, I have checked that in other contexts where we close the scanner in
case of exception, we still call the coprocessor methods.
Ok. If you have verified it then it is fine.
Thanks a lot [~enis].

bq. Now the client on seeing this exception will try to retry this Exception.
Since the scanner is removed from the scanner's map and already we have a
scannerId associated with the scan request,
No, both UnknownScannerException and ScannerResetException extend
DoNotRetryIOException, client will not retry with the same scanner id. This
means that the RPC retrying mechanism (RPCRetryingCaller,
ScannerCallableWithReplicas, etc) is not gonna be retried. However, at a higher
level, there is a retry-from-where-you-are-left mechanism within ClientScanner.
Thus, ClientScanner will re-open a new RegionScanner by sending a new scan
request and get a new scanner name. This logic is in ClientScanner:
{code}
// If exception is any but the list below throw it back to the client; else
setup
// the scanner and retry.
Throwable cause = e.getCause();
if ((cause != null && cause instanceof NotServingRegionException) ||
(cause != null && cause instanceof RegionServerStoppedException) ||
e instanceof OutOfOrderScannerNextException ||
e instanceof UnknownScannerException ||
e instanceof ScannerResetException) {
// Pass. It is easier writing the if loop test as list of what is
allowed rather than
// as a list of what is not allowed... so if in here, it means we do
not throw.
} else {
throw e;
}
{code}
The client will also toss-away any partial results so far, and continue the
scan from the last known row.
bq. ->In case of actual retries whether the scanner internals and its heap are
reset properly
The heap will be reset correctly, because the region scanner is closed for
good. A completely new RegionScanner will be constructed from scratch.
bq. -> In case my retries are over how am I cleaning up the heap and also the
blocks. This will happen only for master branch I think and we need to fix only
in 2.0.
We close the scanner and remove the lease already. We set the rpcCallback which
will get run and call shipped(), no? Is it the case that if the scanner is
already closed, shipped() will not free up the blocks?
bq. One more thing is that since closeScanner is getting called even on
exception the CP hooks preScannerClose and postScannerClose are getting called.
Is that expected?
Yes, I have checked that in other contexts where we close the scanner in case
of exception, we still call the coprocessor methods.

[~devaraj] any more concerns with the patch. The test failures are due to
flakiness.

[jira] [Commented] (HBASE-16604) Scanner retries on IOException can cause the scans to miss data
[

Devaraj Das commented on HBASE-16604:
-
Very good find, [~enis]. On the patch, just a thought - should we treat the
ScannerResetException the same way as the UnknownScannerException (in terms of
checking timeout) in ClientScanner. That way, if the client's scannertimeout
has expired, the client gets back an exception. Saying this, because if the
IOException happened due to an underlying filesystem issue, the data might be
unavailable for a longer duration (which might cause other bigger issues but
still), and multiple retries may or may not help...

Some more info.
KeyValueHeap.generalizedSeek() will leave the heap in "dirty" state by setting
the {{current = null}} if it gets an IOException:
{code }
private boolean generalizedSeek(boolean isLazy, Cell seekKey,
boolean forward, boolean useBloom) throws IOException {
if (!isLazy && useBloom) {
throw new IllegalArgumentException("Multi-column Bloom filter " +
"optimization requires a lazy seek");
}
if (current == null) {
return false;
}
heap.add(current);
current = null;
...
{code}
On the next call, this will return false, indicating that there are no more
values to return.
We can deal with this in a couple of different ways:
(1) Handle IOExceptions in individual KVHeap methods and make sure that state
is left consistent even in case of IOExceptions.
(2) Handle IOExceptions in HRegionScannerImpl and reset the whole RegionScanner
state before returning
(3) Bubble the exception to the client, but make sure that the scanner is
thrown away. The client will restart another RegionScanner, and possibly start
from scanning from the start of the row throwing away partial results.
I think, doing (1) will be very fragile. (2) also will not work, since there
should be a way to reset the scanner state reliable in case of an IOException
coming deep down from FS layer. If we are doing partial results, we maybe left
in the middle of a row, but with partially seek'ed. Thus I think (2) also won't
cut.
(3) is the simplest, which would reset the scanner back to the start of the
row, and makes sure that the ScannerCallable returns. The challenge with (3) is
that, we want the ScannerCallable to not retry, but we want the ClientScanner
to retry. ClientScanner only handles a couple of known exceptions which are
derivatives of DNRIOE (UnknownScannerException, NotServingRegionException,
OutOfOrderScannerNextException, etc). We can introduce another exception type
(ResetScannerException), but we have to be careful for BC for existing clients.

Notice in the above that after the ScannerCallable gets the IOException, the
ScannerCallableWithReadReplicas layer retries the same RPC with the same
scanner {{next_call_seq}}. That retry call returns with
{{more_results_in_region: false}}:
