Hyukjin Kwon commented on SPARK-23831: -------------------------------------- Because it caused a problem that Hive enabled session is restarted. I talked with [~yumwang] and looks it does not fix an actual usecase but the fix breaks one actual usecase. The fix and root causes were not perfectly understood so I rather reverted. Is there an actual case broken or fixed by this PR? If so, I don't object to revert this as I explained in the PR. > Add org.apache.derby to IsolatedClientLoader > -------------------------------------------- > > Key: SPARK-23831 > URL: https://issues.apache.org/jira/browse/SPARK-23831 > Project: Spark > Issue Type: Improvement > Components: SQL > Affects Versions: 2.4.0 > Reporter: Yuming Wang > Priority: Major > > Add org.apache.derby to IsolatedClientLoader,otherwise it may throw an > exception: > {noformat} > [info] Cause: java.sql.SQLException: Failed to start database 'metastore_db' > with class loader > org.apache.spark.sql.hive.client.IsolatedClientLoader$$anon$1@2439ab23, see > the next exception for details. > [info] at > org.apache.derby.impl.jdbc.SQLExceptionFactory.getSQLException(Unknown Source) > [info] at > org.apache.derby.impl.jdbc.SQLExceptionFactory.getSQLException(Unknown Source) > [info] at org.apache.derby.impl.jdbc.Util.seeNextException(Unknown Source) > [info] at org.apache.derby.impl.jdbc.EmbedConnection.bootDatabase(Unknown > Source) > [info] at org.apache.derby.impl.jdbc.EmbedConnection.<init>(Unknown Source) > [info] at org.apache.derby.jdbc.InternalDriver$1.run(Unknown Source) > {noformat} > How to reproduce: > {noformat} > sed 's/HiveExternalCatalogSuite/HiveExternalCatalog2Suite/g' > sql/hive/src/test/scala/org/apache/spark/sql/hive/HiveExternalCatalogSuite.scala > > > sql/hive/src/test/scala/org/apache/spark/sql/hive/HiveExternalCatalog2Suite.scala > build/sbt -Phive "hive/test-only *.HiveExternalCatalogSuite > *.HiveExternalCatalog2Suite" > {noformat} -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
