Known Issues and Limitations
- MapR does not support the integration between Hue 4.2.0 and the following components:
- Solr Search
- ZooKeeper
- Integration between Hue 4.2.0 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.
- MAPR-28087: Livy cannot use the Hive Interpreter. To work around this issue, use the
cluster mode. Set
livy.spark.deployMode=cluster
in the{LIVY_CONF}/livy.conf
file. This issue is caused by Spark 11851: "Unable to start spark thrift server against secured hive metastore(GSS initiate failed)". - MHUE-209 Hue cannot create a table from *.csv file via importer from ADLS.
NOTE Hue uses python parquet lib to read parquet files. This library does not
support all possible parquet formats.
- LIVY-42: Livy UI is not accessible on Kerberos.
- MHUE-302: Broken link to Table Browser in table description in left assistant panel.
- MHUE-303: Integration of Table Browser with Drill is not supported.NOTE When the
[notebook]
section of thehue.ini
contains a Drill entry that precedes the Hive entry, the Table Browser uses the Drill back end. This can be turned off by settingforce_hs2_metadata=true
in the[metastore]
section of thehue.ini
.
Resolved Issues
- None.
