> Reported by Kiran in this thread: "HBase file encryption, inconsistencies
> observed and data loss"
> After step 4 ( i.e disabling of WAL encryption, removing
> SecureProtobufReader/Writer and restart), read of encrypted WAL fails mainly
> due to EOF exception at Basedecoder. This is not considered as error and
> these WAL are being moved to /oldWALs.
> Following is observed in log files:

> is corrupted = false progress failed = false
> {code}
> To fix this, we need to propagate EOF exception to HLogSplitter. Any
> suggestions on the fix?
> -------- (end of quote from Kiran)
> In BaseDecoder#rethrowEofException() :
> {code}
> if (!isEof) throw ioEx;
> LOG.error("Partial cell read caused by EOF: " + ioEx);
> EOFException eofEx = new EOFException("Partial cell read");
> eofEx.initCause(ioEx);
> throw eofEx;
> {code}
> throwing EOFException would not propagate the "Partial cell read" condition
> to HLogSplitter which doesn't treat EOFException as an error.
> I think IOException should be thrown above - HLogSplitter#getNextLogLine()
> would translate the IOEx to CorruptedLogFileException.
