Hi
I posted this on the user list yesterday, I am posting it here now because on
further investigation I am pretty sure this is a bug:
On upgrade from 1.5.0 to 1.6.0 I have a problem with the hivethriftserver2, I
have this code:
val hiveContext = new HiveContext(SparkContext.getOrCreate(conf));
val thing =
hiveContext.read.parquet("hdfs://dkclusterm1.imp.net:8020/user/jegreen1/ex208")
thing.registerTempTable("thing")
HiveThriftServer2.startWithContext(hiveContext)
When I start things up on the cluster my hive-site.xml is found – I can see
that the metastore connects:
INFO metastore - Trying to connect to metastore with URI
thrift://dkclusterm2.imp.net:9083
INFO metastore - Connected to metastore.
But then later on the thrift server seems not to connect to the remote hive
metastore but to start a derby instance instead:
INFO AbstractService - Service:CLIService is started.
INFO ObjectStore - ObjectStore, initialize called
INFO Query - Reading in results for query
"org.datanucleus.store.rdbms.query.SQLQuery@0" since the connection used is
closing
INFO MetaStoreDirectSql - Using direct SQL, underlying DB is DERBY
INFO ObjectStore - Initialized ObjectStore
INFO HiveMetaStore - 0: get_databases: default
INFO audit - ugi=jegreen1 ip=unknown-ip-addr cmd=get_databases:
default
INFO HiveMetaStore - 0: Shutting down the object store...
INFO audit - ugi=jegreen1 ip=unknown-ip-addr cmd=Shutting down the
object store...
INFO HiveMetaStore - 0: Metastore shutdown complete.
INFO audit - ugi=jegreen1 ip=unknown-ip-addr cmd=Metastore shutdown
complete.
INFO AbstractService - Service:ThriftBinaryCLIService is started.
INFO AbstractService - Service:HiveServer2 is started.
On 1.5.0 the same bit of the log reads:
INFO AbstractService - Service:CLIService is started.
INFO metastore - Trying to connect to metastore with URI
thrift://dkclusterm2.imp.net:9083 ******* ie 1.5.0 connects to remote hive
INFO metastore - Connected to metastore.
INFO AbstractService - Service:ThriftBinaryCLIService is started.
INFO AbstractService - Service:HiveServer2 is started.
INFO ThriftCLIService - Starting ThriftBinaryCLIService on port 10000 with
5...500 worker threads
So if I connect to this with JDBC I can see all the tables on the hive server –
but not anything temporary – I guess they are going to derby.
I see someone on the databricks website is also having this problem.
Thanks
James
