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\ x11www.infolinks.com\x08tagcloud\x00\x00\x01F-\x83\xB0\x88\x04, lastkey=\x00R20140523_org.cinetux\x09/2013/11/ver-pelicula-caza-al-asesino-online-gratis-2013.html\x03gen\x03WMQ\x00\x00\x00\x05\x02VE\x03901\x010\x0Cfacebook.com\x08tagcloud\x00\x00\x01F-\x83\xB0\x88\x04 at 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 ?
