Marta Kuczora created HIVE-15282:
------------------------------------
Summary: Different modification times are used when an index is built and when its staleness is checked
Key: HIVE-15282
URL: https://issues.apache.org/jira/browse/HIVE-15282
Project: Hive
Issue Type: Bug
Components: Indexing
Affects Versions: 2.1.0
Reporter: Marta Kuczora
Assignee: Marta Kuczora
The index_auto_mult_tables and index_auto_mult_tables_compact q tests are failing from time to time with the following error:
{noformat}
org.apache.hadoop.hive.cli.TestCliDriver.testCliDriver_index_auto_mult_tables
Failing for the past 1 build (Since Failed#16 )
Took 16 sec.
Error Message
Unexpected exception junit.framework.AssertionFailedError: Client Execution results failed with error code = 1
See ./ql/target/tmp/log/hive.log or ./itests/qtest/target/tmp/log/hive.log, or check ./ql/target/surefire-reports or ./itests/qtest/target/surefire-reports/ for specific test cases logs.

Failed query: index_auto_mult_tables.q
{noformat}
From the output of the failing test, it seems that the index on the srcpart table is not used.
The hive.log contains the following:
{noformat}
2016-11-07T02:47:45,992 INFO [6401ee51-9d53-4101-a14e-9067d0bc357d main] index.IndexWhereProcessor: checking index staleness...
2016-11-07T02:47:45,998 INFO [6401ee51-9d53-4101-a14e-9067d0bc357d main] index.IndexWhereProcessor: Index is stale on partition 'ds=2008-04-09/hr=11'. Modified time (1478515600000) for 'pfile:/home/hiveptest/54.215.115.117-hiveptest-0/apache-github-source-source/itests/qtest/target/warehouse/srcpart/ds=2008-04-09/hr=11/kv1.txt' is higher than index creation time (1478515599000).
{noformat}
The staleness check fails for the index on the srcpart table for the ds=2008-04-09/hr=11 partition, so the index is really not used. The staleness check fails, because the modification time of the itests/qtest/target/warehouse/srcpart/ds=2008-04-09/hr=11/kv1.txt file (11:46:40:0) is higher than the index creation time (11:46:39:0).
After some investigation, I found that this happens if the creation of the partition folder and moving the kv1.txt file happens when the second turns. So the folder is created at 11:46:39,961, but the MoveTask which moves the kv1.txt file to the folder starts at 11:46:39:961 and finishes at 11:46:40,012.

In this case, the last modification time of the folder itests/qtest/target/warehouse/srcpart/ds=2008-04-09/hr=11/ will be 11:46:39 and of the kv1.txt will be 11:46:40.
When the index is built in the DDLTask.alterIndex method, the modification time which is stored for each partition is the modification time of the folder:
{noformat}
if (baseTbl.isPartitioned()) {
List<Partition> baseParts;
if (alterIndex.getSpec() != null) {
baseParts = db.getPartitions(baseTbl, alterIndex.getSpec());
} else {
baseParts = db.getPartitions(baseTbl);
}
if (baseParts != null) {
for (Partition p : baseParts) {
FileSystem fs = p.getDataLocation().getFileSystem(db.getConf());
FileStatus fss = fs.getFileStatus(p.getDataLocation());
basePartTs.put(p.getSpec(), fss.getModificationTime());
}
}
} else {
{noformat}
But when the staleness is checked in the IndexUtils.isIndexPartitionFresh method, it checks the modification time of the files in the partition folder:
{noformat}
private static boolean isIndexPartitionFresh(Hive hive, Index index,
Partition part) throws HiveException {
LOG.info("checking index staleness...");
try {
String indexTs = index.getParameters().get(part.getSpec().toString());
if (indexTs == null) {
return false;
}
FileSystem partFs = part.getDataLocation().getFileSystem(hive.getConf());
FileStatus[] parts = partFs.listStatus(part.getDataLocation(), FileUtils.HIDDEN_FILES_PATH_FILTER);
for (FileStatus status : parts) {
if (status.getModificationTime() > Long.parseLong(indexTs)) {
LOG.info("Index is stale on partition '" + part.getName()
+ "'. Modified time (" + status.getModificationTime() + ") for '" + status.getPath()
+ "' is higher than index creation time (" + indexTs + ").");
return false;
}
}
} catch (IOException e) {
throw new HiveException("Failed to grab timestamp information from partition '" + part.getName() + "': " + e.getMessage(), e);
}
return true;
}
{noformat}
Because of the modification time of the itests/qtest/target/warehouse/srcpart/ds=2008-04-09/hr=11/kv1.txt file is higher (11:46:40), than the modification time of the itests/qtest/target/warehouse/srcpart/ds=2008-04-09/hr=11 folder (11:46:39), the check fails and the index is not used which leads to the failure of the q test.
