Exception when no splits returned from index
--------------------------------------------
Key: HIVE-2138
URL: https://issues.apache.org/jira/browse/HIVE-2138
Project: Hive
Issue Type: Bug
Components: Indexing
Affects Versions: 0.8.0
Reporter: Russell Melick
Running a query that uses indexing but doesn't return any results give an
exception.
{code} java.lang.IllegalArgumentException: Can not create a Path from an empty
string
at org.apache.hadoop.fs.Path.checkPathArg(Path.java:82)
at org.apache.hadoop.fs.Path.<init>(Path.java:90)
at org.apache.hadoop.util.StringUtils.stringToPath(StringUtils.java:224)
at
org.apache.hadoop.mapred.FileInputFormat.setInputPaths(FileInputFormat.java:282)
at
org.apache.hadoop.hive.ql.index.HiveIndexedInputFormat.getSplits(HiveIndexedInputFormat.java:123)
{code}
This could potentially be fixed by creating a new empty file to use for the
splits.
Once this is fixed, the index_auto_test_if_used.q can be used.
