Hello, I keep getting this message while running the 'completebulkload' process. I tried the following solutions that I came across while Googling for this error:
1) setReduceSpeculativeExecution(true) 2) Made sure that none of the tasks are failing. 3) The HFileOutput job runs successfully. 4) The first 2 lines in the output from HFileOutput look like this: 2b 39 4c 39 39 2f 2b 2b 4d 57 54 37 66 32 2b 32 2a 31 2a 31 35 33 33 34 37 2a 34 39 39 39 row=+9L99/++MWT7f2+2*1*153347*4999, families={(family=info, keyvalues=(+9L99/++MWT7f2+2*1*153347*4999/info:frequency/9223372036854775807/Put/vlen=1)} 2b 39 4c 39 39 2f 2b 2b 4d 57 54 37 66 32 2b 32 2a 31 2a 31 35 33 33 34 38 2a 34 39 39 39 row=+9L99/++MWT7f2+2*1*153348*4999, families={(family=info, keyvalues=(+9L99/++MWT7f2+2*1*153348*4999/info:frequency/9223372036854775807/Put/vlen=1)} 5) My Mapper for HFileOutput looks like this: public static class MyMapper extends MapReduceBase implements Mapper<LongWritable, Text, ImmutableBytesWritable, Put> { @Override public void map(LongWritable key, Text value, OutputCollector<ImmutableBytesWritable, Put> output, Reporter reporter) throws IOException { String[] values = value.toString().split("\t"); String key1 = values[0]; String value1 = values[1]; ImmutableBytesWritable ibw = new ImmutableBytesWritable(key1.getBytes()); Put put = new Put(Bytes.toBytes(key1)); put.add(Bytes.toBytes("info"), Bytes.toBytes("frequency"), Bytes.toBytes(value1)); output.collect(ibw, put); } } Any ideas what could be wrong? Thanks for your help.
