Known Issues and Limitations

  • MapR does not support the integration between Hue 3.12.0 and the following components:
    • Solr Search
    • ZooKeeper
  • Integration between Hue 3.12.0 and Sentry 1.7 is supported on secure clusters that use Kerberos authentication, but it is not supported on secure clusters that use MapR-SASL authentication.
  • MAPR-2561: DB Query in Hue cannot execute more than one query.
  • HUE-6074: [notebook] Execute snippets as Oozie batch.
  • MAPR-28087: Livy cannot use the Hive Interpreter. To work around this issue, use cluster mode. Set livy.spark.deployMode=cluster in {LIVY_CONF}/livy.conf. This issue is caused by Spark 11851 ("Unable to start spark thrift server against secured hive metastore(GSS initiate failed").
Note: Hue uses python parquet lib to read the parquet files. This library does not support all possible parquet formats.

Resolved Issues

  • None.
