Here's my review of the configuration parameters in HiveConf.java, patch 2. # Why did you remove four comment lines starting with "// Hadoop Configuration Properties"? # Formatting: For hive.server2.customized.udf.jars.path and hive.server2.customized.udf.properties please insert newlines (\n) in the descriptions as shown on lines 324 and 325, start the description of hive.server2.customized.udf.jars.path on a new line, and use standard indenting. # Capitalization: For hive.server2.customized.udf.jars.path please change "The path on hdfs" to "The path on HDFS" and "means the hdfs path" to "means the HDFS path". # Edit: For hive.server2.customized.udf.jars.path please change "When hdfs:// missing" to "When hdfs:// is missing". # Edits: For hive.server2.customized.udf.properties please change "customized udf" to "customized UDF", change "defination" to "definition", change "It's must be under $" to "It must be under the $", and change "The patern is as below." to "The pattern is".

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.

The implementation is improve CLIService.java and CliDriver.java. When
connecting hive throw thrift, CLIService will call function
initCustomUDF(SessionHandle sessionHandle), this will load all functions
configged in hive-udf.properties, which is a custom defined properties file
underlying $HIVE_HOME/conf. Actully, hive-udf.properties can be renamed in

liuzongquan commented on HIVE-11663:
when add a custom udf that want to be used in hiveserver2 and hive cli, you
just upload the UDF jar file on to ${hive.server2.customized.udf.jar.path},
which is a hdfs:// path. And then, append the udf properties to
hive-udf.properties as following.
# mls udf
multi_concat={com.meilishuo.hive.udf.jar,com.meilishuo.hive.udf.UDFMultiConcat}
unfold={com.meilishuo.hive.udf.jar,com.meilishuo.hive.udf.UDFUnfoldURL}

That's all you do for new custom UDF! And the hiveserver2 can use them
immediately！
