--------------------------------
Hi, [~ashutoshc]
The fix doesn't affect because the variable partitions is empty.
{code:java}
case DYNAMIC_PARTITION:
for (Partition
dynPart:tableScanOp.getConf().getTableMetadata().getTableSpec().partitions) {
inputPaths.add(dynPart.getDataLocation());
}
break;
{code}
The "partitions" is set in Hive.getPartitionsByNames().
{code:java}
public List<Partition> getPartitionsByNames(Table tbl,
Map<String, String> partialPartSpec)
throws HiveException {
if (!tbl.isPartitioned()) {
throw new HiveException(ErrorMsg.TABLE_NOT_PARTITIONED,
tbl.getTableName());
}
// the size of names is 0;
List<String> names = getPartitionNames(tbl.getDbName(), tbl.getTableName(),
partialPartSpec, (short)-1);
List<Partition> partitions = getPartitionsByNames(tbl, names);
return partitions;
}
{code}

> Project: Hive
> Issue Type: Improvement
> Components: Query Processor
> Affects Versions: 0.14.0, 1.0.0

> Priority: Minor

> HIVE-3958 added support for partial scan for RCFile. This works fine for
> static partitions (for example: analyze table analyze_srcpart_partial_scan
> PARTITION(ds='2008-04-08',hr=11) compute statistics partialscan).
> For dynamic partition, the analyze files with an IOException
> "java.io.IOException: No input paths specified in job":
> hive> ANALYZE TABLE testtable PARTITION(col_varchar) COMPUTE STATISTICS
> PARTIALSCAN;
> java.io.IOException: No input paths specified in job
