[SPARK-27402][SQL][test-hadoop3.2][test-maven] Fix hadoop-3.2 test issue(except the hive-thriftserver module) #24391

wangyum · 2019-04-17T06:47:45Z

What changes were proposed in this pull request?

This pr fix hadoop-3.2 test issues(except the hive-thriftserver module):

Add hive.metastore.schema.verification and datanucleus.schema.autoCreateAll to HiveConf.
hadoop-3.2 support access the Hive metastore from 0.12 to 2.2

After SPARK-27176 and this PR, we upgraded the built-in Hive to 2.3 when enabling the Hadoop 3.2+ profile. This upgrade fixes the following issues:

HIVE-6727: Table level stats for external tables are set incorrectly.
HIVE-15653: Some ALTER TABLE commands drop table stats.
SPARK-12014: Spark SQL query containing semicolon is broken in Beeline.
SPARK-25193: insert overwrite doesn't throw exception when drop old data fails.
SPARK-25919: Date value corrupts when tables are "ParquetHiveSerDe" formatted and target table is Partitioned.
SPARK-26332: Spark sql write orc table on viewFS throws exception.
SPARK-26437: Decimal data becomes bigint to query, unable to query.

How was this patch tested?

This pr test Spark’s Hadoop 3.2 profile on jenkins and #24591 test Spark’s Hadoop 2.7 profile on jenkins

This PR close #24591

            dep.dependent_modules.add(self)
-        all_modules.append(self)
+        if name == "hive-thriftserver" and hadoop_version == "hadoop3.2":


Used to skip hive-thriftserver module for hadoop-3.2. Will revert this change once we can merge.

Maybe leave a TODO here just to try to make sure that doesn't get lost

We should have a log message to show which profile we are using; otherwise, it is hard for us to know which profile is activated.

Yes. we already have these log message:

https://amplab.cs.berkeley.edu/jenkins/job/SparkPullRequestBuilder/105106/consoleFull

What I mean, we should have a log message to show which profile is being actually used.

Just relying on the command parameter lists does not sound very reliable

OK. updated to:

+    hiveConf.setBoolean("hive.metastore.schema.verification", false)
+    hiveConf.setBoolean("datanucleus.schema.autoCreateAll", true)


Could you add a test case to ensure that we still respect the values set from users?

For example, if users set a different value, we do not reset them to our values.

I update it to:

def conf: HiveConf = { val hiveConf = state.getConf // Hive changed the default of datanucleus.schema.autoCreateAll from true to false // and hive.metastore.schema.verification from false to true since Hive 2.0. // For details, see the JIRA HIVE-6113, HIVE-12463 and HIVE-1841. // For the production environment. Either isDefaultMSUri or isDerbyMS should not be true. // We hard-code hive.metastore.schema.verification and datanucleus.schema.autoCreateAll to allow // bin/spark-shell, bin/spark-sql and sbin/start-thriftserver.sh to automatically create the // Derby Metastore when running Spark in the non-production environment. val isDefaultMSUri = hiveConf.getVar(METASTOREURIS).equals(METASTOREURIS.defaultStrVal) val isDerbyMS = hiveConf.getVar(METASTORECONNECTURLKEY).startsWith("jdbc:derby") if (isDefaultMSUri && isDerbyMS) { hiveConf.setBoolean("hive.metastore.schema.verification", false) hiveConf.setBoolean("datanucleus.schema.autoCreateAll", true) } hiveConf }

Because we don't know it's default value or set by user. so just set it for non-production environment.

My review is finished. Overall, it looks good to me. After we ensure that maven can pass all the tests, we also need to rerun SBT as well.
