It looks like HBase is giving up trying to create a writer... The
lastIOE is probably an exception generated by CephFileSystem. Would it
be possible to add some debug info so we could see where the exception
is coming from? This try block seems to be masking that.
public Writer createWriter(FileSystem fs, Configuration conf, Path
hlogFile) throws IOException {
int i = 0;
IOException lastIOE = null;
do {
try {
return HLog.createWriter(fs, hlogFile, conf);
} catch (IOException ioe) {
lastIOE = ioe;
sleepBeforeRetry("Create Writer", i+1);
}
} while (++i <= hdfsClientRetriesNumber);
throw new IOException("Exception in createWriter", lastIOE);
