Usability issues

This topic lists some common exceptions and errors that you may encounter while using Kudu and helps you to resolve issues related to usability.

ClassNotFoundException: com.cloudera.kudu.hive.KuduStorageHandler
You will encounter this exception when you try to access a Kudu table using Hive. This is not a case of a missing jar, but simply that Impala stores Kudu metadata in Hive in a format that is unreadable to other tools, including Hive itself. and Spark. Currently, there is no workaround for Hive users. Spark users can work around this by creating temporary tables.
Runtime error: Could not create thread: Resource temporarily unavailable (error 11)
You may encounter this error when Kudu is unable to create more threads, usually on versions older than Kudu 1.7. It happens on tablet servers, and is a sign that the tablet server hosts too many tablet replicas.
