Error Unable to instantiate

Question

Can someone suggest how to come out from the below error?

error:

org.apache.hadoop.hive.metastore.HiveMetaStoreClient

Answer 1

Hi,

 There is a possibility that because of the following reasons above error may occur:

1. While we use derby metastore, Then lock file would be there in case of the abnormal exit.

Hence, do remove the lock file with the help of below command:

rm metastore_db/*.lck​

2. Moreover, Run hive in Debug mode with the help of this command below:

hive -hiveconf hive.root.logger=DEBUG,console
