Hi, I'm working on custom sql processing on top of Spark-SQL, and i'm upgrading it along with spark 1.4.1. I've got an error regarding multiple test suites access hive meta store at the same time like :
Cause: org.apache.derby.impl.jdbc.EmbedSQLException: Another instance of Derby may have already booted the database /Users/~~~/metastore_db. at org.apache.derby.impl.jdbc.SQLExceptionFactory.getSQLException(Unknown Source) at org.apache.derby.impl.jdbc.SQLExceptionFactory40.wrapArgsForTransportAcrossDRDA(Unknown Source) at org.apache.derby.impl.jdbc.SQLExceptionFactory40.getSQLException(Unknown Source) at org.apache.derby.impl.jdbc.Util.generateCsSQLException(Unknown Source) at org.apache.derby.impl.jdbc.EmbedConnection.bootDatabase(Unknown Source) at org.apache.derby.impl.jdbc.EmbedConnection.<init>(Unknown Source) at org.apache.derby.impl.jdbc.EmbedConnection40.<init>(Unknown Source) at org.apache.derby.jdbc.Driver40.getNewEmbedConnection(Unknown Source) at org.apache.derby.jdbc.InternalDriver.connect(Unknown Source) at org.apache.derby.jdbc.Driver20.connect(Unknown Source) It was okay with spark 1.3.0. Any idea to fist this? thanks in advance. Jason
