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.
