Here's a list of 49 configuration parameters in RC0 (and trunk) that don't have descriptions in hive-default.xml.template:
*Release 1 or 2 * hive.exec.submitviachild hive.metastore.metadb.dir hive.jar.path hive.aux.jars.path hive.table.name hive.partition.name hive.alias *Release 3 * hive.cli.errors.ignore *Release 4 * hive.added.files.path hive.added.jars.path *Release 5 * hive.intermediate.compression.codec hive.intermediate.compression.type hive.added.archives.path *Release 6 * hive.metastore.archive.intermediate.archived hive.metastore.archive.intermediate.extracted hive.mapred.partitioner hive.exec.script.trust hive.hadoop.supports.splittable.combineinputformat *Release 7 * hive.lockmgr.zookeeper.default.partition.name hive.metastore.fs.handler.class hive.query.result.fileformat hive.hashtable.initialCapacity hive.hashtable.loadfactor hive.debug.localtask hive.lock.manager hive.outerjoin.supports.filters hive.semantic.analyzer.hook *Release 8 * hive.exec.job.debug.timeout hive.exec.tasklog.debug.timeout hive.merge.rcfile.block.level hive.merge.input.format.block.level hive.merge.current.job.has.dynamic.partitions hive.stats.collect.rawdatasize *Release 8.1 * hive.optimize.metadataonly *Release 9 * *Release 10 * *Release 11 * hive.exec.rcfile.use.sync.cache hive.stats.key.prefix --- *internal* *Release 12 * hive.scratch.dir.permission datanucleus.fixedDatastore datanucleus.rdbms.useLegacyNativeValueStrategy hive.optimize.sampling.orderby --- *internal?* hive.optimize.sampling.orderby.number hive.optimize.sampling.orderby.percent hive.server2.authentication.ldap.Domain hive.server2.session.hook hive.typecheck.on.insert *Release 13 * hive.metastore.expression.proxy hive.txn.manager hive.stageid.rearrange hive.explain.dependency.append.tasktype What's the best way to deal with these? 1. Ignore them (or identify those that can be ignored). 2. Add some descriptions in Hive 0.13.0 RC1. 3. Deal with them after HIVE-6037<https://issues.apache.org/jira/browse/HIVE-6037>gets committed. - Try to cover all of them by Hive 0.14.0: - Put the list in a JIRA and create a common HiveConf.java patch, which can be appended until release 0.14.0 is ready. - Accumulate descriptions in JIRA comments, then create a patch from the comments. - Deal with them as soon as possible: - Put the list in an umbrella JIRA and use sub-task JIRAs to add descriptions individually or in small groups. 4. Deal with them in the wiki, then patch HiveConf.java before release 0.14.0. 5. [Your idea goes here.] -- Lefty
