Tsz Wo (Nicholas), SZE updated HDFS-3181:
-----------------------------------------
Attachment: h3181_20120425.patch
The test writes one byte outside the try-block but an exception is thrown.
h3181_20120425.patch:
{code}
// make sure that the client can't write data anymore.
- stm.write('b');
try {
+ stm.write('b');
stm.hflush();
fail("Should not be able to flush after we've lost the lease");
} catch (IOException e) {
- LOG.info("Expceted exception on hflush", e);
+ LOG.info("Expceted exception on write/hflush", e);
}
{code}
> testHardLeaseRecoveryAfterNameNodeRestart fails when length before restart is
> 1 byte less than CRC chunk size
