Subject Added a key not lexically larger than previous key
Date Sun, 25 May 2014 09:02:44 GMT
I'm running HBase 0.94.12 (Hadoop 1.0.4).
I have a daily bulk load job that runs for a long time now, suddenly I got
this exception:

java.io.IOException: Added a key not lexically larger than previous
key=\x00U20140523]org.cinetux\x09/2013/11/ver-pelicula-charlie-countryman-online-gratis-2013.html\x03gen\x03WMQ\x00\x00\x00\x05\x02MX\x0210\x010\

org.apache.hadoop.hbase.io.hfile.AbstractHFileWriter.checkKey(AbstractHFileWriter.java:207)
..........

I'm running with configureIncrementalLoad() and using
ImmutableBytesWritable as key and Put as value (leads to using
PutSortReducer).

The weird thing is after I re-executed the same job, it worked just fine,
no exceptions...

While I'm happy it works now, I really don't understand what could go wrong
there ?
