Nick Dimiduk resolved HBASE-24271. ---------------------------------- Release Note: <!-- markdown --> HBASE-24271 makes changes the the default `conf/hbase-site.xml` such that `bin/hbase` will run directly out of the binary tarball or a compiled source tree without any configuration modifications vs. Hadoop 2.8+. This changes our long-standing history of shipping no configured values in `conf/hbase-site.xml`, so existing processes that assume this file is empty of configuration properties may require attention. Resolution: Fixed > Set values in `conf/hbase-site.xml` that enable running on `LocalFileSystem` > out of the box > ------------------------------------------------------------------------------------------- > > Key: HBASE-24271 > URL: https://issues.apache.org/jira/browse/HBASE-24271 > Project: HBase > Issue Type: Task > Affects Versions: 3.0.0-alpha-1, 2.3.0, 1.7.0, 2.2.4 > Reporter: Nick Dimiduk > Assignee: Nick Dimiduk > Priority: Major > Fix For: 3.0.0-alpha-1, 2.3.0, 1.7.0, 2.2.5 > > > This ticket is to implement the changes as described on the [discussion on > dev|https://lists.apache.org/thread.html/r089de243a9bc9d923fa07c81e6bc825b82be68f567b892a342a0c61f%40%3Cdev.hbase.apache.org%3E]. > It reverts and supersedes changes made on HBASE-24086 and HBASE-24106. > {quote} > The conclusion I understand from this thread looks something like this: > 1. revert HBASE-24086, make it so that running on `LocalFileSystem` is a > fatal condition with default configs. > 2. ship a conf/hbase-site.xml that contains > hbase.unsafe.stream.capability.enforce=false, along with a big comment saying > this is not safe for production. > 3. ship a conf/hbase-site.xml that contains hbase.tmp.dir=./tmp, along with a > comment saying herein you'll find temporary and persistent data, reconfigure > for production with hbase.rootdir pointed to a durable filesystem that > supports our required stream capabilities (see above). > 4. update HBASE-24106 as appropriate. > Neither 2 nor 3 are suitable for production deployments, thus the changes do > not go into hbase-default.xml. Anyone standing up a production deploy must > edit hbase-site.xml anyway, so this doesn't change anything. It also restores > our "simple" first-time user experience of not needing to run anything > besides `bin/start-hbase.sh` (or `bin/hbase master start`, or whatever it is > we're telling people these days). > We can reassess this once more when a durable equivalent to LocalFileSystem > comes along. > {quote} -- This message was sent by Atlassian Jira (v8.3.4#803005)
