Subject Re: Error loading SHA-1 keys with load bulk
Date Thu, 01 May 2014 22:42:41 GMT
Yes, I do,


            job.setMapperClass(EventMapper.class);
            job.setMapOutputKeyClass(ImmutableBytesWritable.class);
            job.setMapOutputValueClass(KeyValue.class);

            FileOutputFormat.setOutputPath(job, hbasePath);
            HTable table = new HTable(jConf, MEM_TABLE_HBASE);
            HFileOutputFormat.configureIncrementalLoad(job, table);


The error is happeing in a MRUnit, I don't know if it changes something
about the behavior, because I had some troubles in the past for the same
reason about the serialization in Hbase 0.96 and MRUnit.
. Besides, in the setup of the MRUnit test I load some data in hbase with
keys in sha1 and it works.
