Lefty Leverenz commented on HIVE-11663: --------------------------------------- Review comments for the first patch: # conf/hive-default.xml.template is now generated from HiveConf.java (see the WARNING!!! lines in the patch) so it doesn't belong in the patch # many or perhaps all files appear twice in the patch # new configuration parameters in HiveConf.java need editing: #* for *hive.server2.customized.udf.enabled* please change "Whether enable hiveserver add customized udf from adding jars ..." to "Whether to enable HiveServer2 or the Hive CLI to add a customized UDF from a jar file ..." #* for *hive.server2.customized.udf.jars.path* please supply a parameter description (even though it may seem obvious) #* for *hive.server2.customized.udf.properties* change "The customized udf functions' defination file. It's must be under $HIVE_HOME/conf directory. The patern is as below." to "The customized UDF functions' definition file. It must be under the $HIVE_HOME/conf directory. The pattern is as below." #* for *hive.server2.customized.udf.defination.list* change "defination" to "definition" and for HIVE_SERVER2_CUSTOMIZED_UDF_DEFINATION_LIST similarly change "DEFINATION" to "DEFINITION" (also change all occurrences elsewhere in the patch -- I count 26 but that includes the template file and duplicate files) #* for the description of *hive.server2.customized.udf.defination.list* presumably the hive.thrift.customized.* parameters are supposed to be hive.server2.customized.* and other edits are needed: {code} + "The customized UDF functions' definition list. For example, if there is a UDF jar on the \n" + + "${hive.server2.customized.udf.jars.path} containing a foo.bar class which defines a UDF \n" + + "function named test, then you can add \'foo.bar:test\' to the property \n" + + "hive.server2.customized.udf.definition.list. Any additional definitions are separated with commas.\n" + + "Note that this property depends on hive.server2.customized.udf.enabled being set to true." {code} > Auto load/unload custom udf function for hive cli and hiveserver2 > ----------------------------------------------------------------- > > Key: HIVE-11663 > URL: https://issues.apache.org/jira/browse/HIVE-11663 > Project: Hive > Issue Type: Improvement > Components: CLI, Configuration > Affects Versions: 0.14.0, 1.0.0, 1.0.1, 1.1.1, 1.2.1 > Reporter: liuzongquan > Assignee: liuzongquan > Labels: features, patch > Attachments: HIVE-11663.patch > > Original Estimate: 96h > Remaining Estimate: 96h > > when adding custom functions used in hiveserver2, the most method is re-build > the hive source code, re-dist and restart hiveserver2. This way will produce > big cost for service user and cluster manager. The best way, in my opinion, > the custom udf should be like a plugin to the hiveserver2 and hive cli, and > users should be add and remove at run-time, especially for hiveserver2. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
