When dropping a table from the Metastore Manager in HUE, the underlying HDFS files are not removed, which means users can still query the table (tested with Impala). The table was created using the Metastore Manager, and the data was added by running a Spark Action in Oozie (LOAD DATA INPATH... kv1.txt... INTO TABLE...)   While logged in as a HUE superuser, I tried deleting the Hive folder corresponding to the table I wanted to remove, but I received a permission error:   Cannot perform operation. Note: you are a Hue admin but not a HDFS superuser, "hdfs" or part of HDFS supergroup, "supergroup". AccessControlException: Permission denied by sticky bit: user=cloudera, path="/user/hive/warehouse/hivetest2":cloudera2:hive:drwxrwxrwt, parent="/user/hive/warehouse":hive:hive:drwxrwxrwt (error 500)   What do I need to configure so that a HUE superuser can delete from Hive via the File Browser? What do I need to set so that dropping a table from the Metastore Manager deletes the HDFS files?     ... View more

I'm interested in being able to prohibit users from interacting with, or even being aware of the existence of, specific indexes in Solr. For example, when a user in HUE looks at available indexes in HUE, they can only see the indexes they have permission to interact with.   Is this possible with the Cloudera distribution? I'm running CDH 5.10.   Thanks!! ... View more

I have an intermittent issue. I've read the other threads regarding numpy not found on this site and other places on the web to solve my problem, but it keeps coming back after I re-deploy client configurations.   I am running a Spark job through HUE->Oozie and using pyspark's MLlib which requires numpy.   Initially, I read the Cloudera docs and blog indicating to install numpy to each node (Anaconda isn't an option for me). I installed numpy on each node using yum as root (I didn't create a virtual environment for this). This worked. However, I later re-deployed the client configurations through CM for reasons unrelated to this issue, and I received the numpy not found error again.   At this point I went to the configuration page for Spark in CM to set the variables:   PYSPARK_PYTHON=/usr/lib64/python2.7 PYSPARK_DRIVER_PYTHON=/usr/lib64/python2.7   in Spark Service Advanced Configuration Snippet (Safety Valve) for spark-conf/spark-env.sh. Source: https://www.cloudera.com/documentation/enterprise/latest/topics/spark_python.html#concept_qzp_p3s_b5__section_ark_lkn_25   Next, I re-deployed client configurations. It started working again. However, yet again after re-deploying later on for reasons unrelated to this issue, I got numpy not found again.   So it seems that it just keeps coming back and only lasts for one deployment when it does work. I also looked into checking permissions for the python paths, and I don't see any issues there but I may be missing something.   Could this be related to running it through HUE or Oozie? Are the environment variables I set nto the correct paths?   Any help is appreciated. Thanks! ... View more

CDH 5.10   Is there a way to customize which Action Nodes are displayed in the Oozie Workflow Editor in HUE?   For example, say I don't want a user to be able to select the ssh action, or see it there at all. I couldn't find any reference to this in the docs.   The closest thing that appears to be relevant is in the Oozie Dashboard -> Oozie -> gauges It has a value "configuration.action.types" that appear to list action nodes, except it has more listed than what is actually showing up on the editor; I am logged in as a super user when viewing this.   If that is the correct property, how do i modify it (preferably through CDH or Hue)?   Thanks! ...
