Subject Re: Phoenix Pig Integration: Error in readFields java.lang.NegativeArraySizeException: -1
Date Tue, 01 Jul 2014 20:58:33 GMT
I tried one more script:
A = load 'hbase://query/SELECT * from test_table' using
org.apache.phoenix.pig.
PhoenixHBaseLoader('ZK');
grpd = GROUP A BY Rowkey_Prefix_String;
cnt = FOREACH grpd GENERATE group AS Rowkey_Prefix_String,COUNT(A);
DUMP cnt;

Rowkey_Prefix_String is prefix of my composite rowkey.

Again, i got same error:
ERROR org.apache.hadoop.hbase.io.HbaseObjectWritable - Error in readFields
