Summary: "Unable to check name" message
Key: PIG-3481
URL: https://issues.apache.org/jira/browse/PIG-3481
Project: Pig
Issue Type: Bug
Reporter: zhenyingshan
I am trying to run a pig script in Java program, I get the following error
sometimes but not all the time. Here is the snippet of the program and the
exception I've got. I have "/user/root" directory created in hdfs.
----------------------
URL path =
getClass().getClassLoader().getResource("cfg/concatall.py");
LOG.info("CDNResolve2Hbase: reading concatall.py file from " +
path.toString());
pigServer.getPigContext().getProperties().setProperty(PigContext.JOB_NAME,
"CDNResolve2Hbase");
pigServer.registerQuery("A = load '" + inputPath + "' using
PigStorage('\t') as (ip:chararray, do:chararray, cn:chararray, cdn:chararray,
firsttime:chararray, updatetime:chararray);");
pigServer.registerCode(path.toString(),"jython","myfunc");
pigServer.registerQuery("B = foreach A generate
myfunc.concatall('"+ extractTimestamp(inputPath)+"',ip,do,cn), cdn,
SUBSTRING(firsttime,0,8);");
outputTable = "hbase://" + outputTable;
ExecJob job =
pigServer.store("B",outputTable,"org.apache.pig.backend.hadoop.hbase.HBaseStorage('d:cdn
d:dtime')");
