failed to get database default returning NoSuchObjectException

Related searches

When I start spark I get this warnings:

Using Scala version 2.10.5 (OpenJDK 64-Bit Server VM, Java 1.8.0_77)
Type in expressions to have them evaluated.
Type :help for more information.
Spark context available as sc.

16/04/03 15:07:39 WARN ObjectStore: Failed to get database default, returning NoSuchObjectException
SQL context available as sqlContext.

And also when I execute this command: var sqlContext = new org.apache.spark.sql.hive.HiveContext(sc)

I get again this warning:

scala> var sqlContext = new org.apache.spark.sql.hive.HiveContext(sc)
16/04/03 15:04:31 WARN Connection: BoneCP specified but not present in CLASSPATH (or one of dependencies)
16/04/03 15:04:31 WARN Connection: BoneCP specified but not present in CLASSPATH (or one of dependencies)
16/04/03 15:04:35 WARN ObjectStore: Failed to get database default, returning NoSuchObjectException
sqlContext: org.apache.spark.sql.hive.HiveContext = org.apache.spark.sql.hive.HiveContext@13453610

So my question is if you know why this warning is happening and if, although the warning is happening, the command var sqlContext = new org.apache.spark.sql.hive.HiveContext(sc) its working correctly?

BoneCP is a Java JDBC connection pool and it's tries to bind to a JDBC connection and this is why you receive these warnings. You may suppress this kind of warnings by configure the logger level.

Solved: Re: Spark failed to get database default, ObjectStore: Failed to get database default, returning NoSuchObjectException. SQL context available as sqlContext. Is this some bug related to Spark 1.6? The exception " objectStore: failed to get database default, returning NoSuchObjectException" has a background story. We have derby which will act as a default database for hive meta store when a proper hive.metastore.warehouse.location is not specified in your hive-site.xml.

I meet this warning,too as :

"Failed to get database default, returning NoSuchObjectException"

but i can connect to hive correctly,so check your hive-site.xml and i am not sure if this warning will affect the sentry.

Check if you have assigned SQLContext:

sqlContext = pyspark.SQLContext(sc)

  • Thanks for your answer. And the other warning about failed to get database default? Do you know if although the warning is appearing the command works correctly?
  • Why is it returning a NoSuchObjectException! and Failure?
