--------------------------------------------
Bah, finally. Unrelated test-failures.
> HCatSplit repeats information making input split data size huge

> Key: HIVE-9845
> URL: https://issues.apache.org/jira/browse/HIVE-9845
> Project: Hive
> Issue Type: Bug
> Components: HCatalog
> Reporter: Rohini Palaniswamy
> Assignee: Mithun Radhakrishnan

>
> Pig on Tez jobs with larger tables hit PIG-4443. Running on HDFS data which
> has even triple the number of splits(100K+ splits and tasks) does not hit
> that issue.
> {code}
> HCatBaseInputFormat.java:
> //Call getSplit on the InputFormat, create an
> //HCatSplit for each underlying split
> //NumSplits is 0 for our purposes
> org.apache.hadoop.mapred.InputSplit[] baseSplits =
> inputFormat.getSplits(jobConf, 0);
> for(org.apache.hadoop.mapred.InputSplit split : baseSplits) {
> splits.add(new HCatSplit(
> partitionInfo,
> split,allCols));
> }
> {code}
> Each hcatSplit duplicates partition schema and table schema.
