Russell Melick commented on HIVE-1644: -------------------------------------- Unfortunately, having an empty array gives out of bounds exceptions. {{ java.lang.ArrayIndexOutOfBoundsException: 0 [junit] at org.apache.hadoop.mapred.FileInputFormat.setInputPaths(FileInputFormat.java:309) }} I tried looking through the code at other places we call setInputPaths. In a few places, we create a directory by calling {{ Path dir = new Path(System.getProperty("test.data.dir", ".")); FileInputFormat.setInputPaths(job, dir); }} I tried using this, but unfortunately, this also gives an exception. {{ java.io.IOException: cannot find dir = file:/Users/rmelick/hive/ql/mapred in pathToPartitionInfo: [pfile:/Users/rmelick/hive/build/ql/test/data/warehouse/temp] }} The ql/mapred directory does not exist on my computer, but I also tried changing it to just hive/ql, and it also failed with the same exception. I'm not sure if TestFlatFileInputFormat:146 is creating the temp file like you were thinking. I haven't tried doing it like that. > use filter pushdown for automatically accessing indexes > ------------------------------------------------------- > > Key: HIVE-1644 > URL: https://issues.apache.org/jira/browse/HIVE-1644 > Project: Hive > Issue Type: Improvement > Components: Indexing > Affects Versions: 0.8.0 > Reporter: John Sichi > Assignee: Russell Melick > Attachments: HIVE-1644.1.patch, HIVE-1644.10.patch, > HIVE-1644.11.patch, HIVE-1644.12.patch, HIVE-1644.13.patch, > HIVE-1644.14.patch, HIVE-1644.15.patch, HIVE-1644.16.patch, > HIVE-1644.17.patch, HIVE-1644.18.patch, HIVE-1644.2.patch, HIVE-1644.3.patch, > HIVE-1644.4.patch, HIVE-1644.5.patch, HIVE-1644.6.patch, HIVE-1644.7.patch, > HIVE-1644.8.patch, HIVE-1644.9.patch, hive.log > > > HIVE-1226 provides utilities for analyzing filters which have been pushed > down to a table scan.
