Elliot Miller commented on HBASE-20819:
---------------------------------------
h1. Changed Constants in this Patch
h2. Process
To get the list of constants:
{code:java}
echo 'HBaseConstants.constants.sort.each do |c|; puts c; end' | ./bin/hbase
shell
{code}
I repeated this process for commits b556343 (where my branch splits from
master) and cf2aa59 (tip of my branch) and saved the resulting lists to two
separate files. Then I created a diff:
{code:java}
diff -u HBaseConstants-b5563432922268c7a16deacbb51bfba89c0a2aba.txt
HBaseConstants-cf2aa593e590133b0c76d3723b4074b28b55dcc9.txt{code}
I attached the files to this issue for reference.
h2. Result
These constants were removed from the HBaseConstants module in hbase-shell by
this patch:
* CACHE_DATA_IN_L1
* COMPARATOR
* COMPARATOR_IGNORE_REPLICATION
* ENCODE_ON_DISK
* FOREVER
* IS_MOB_BYTES
* IS_ROOT
* LENGTH
* MOB_COMPACT_PARTITION_POLICY_BYTES
* MOB_THRESHOLD_BYTES
* REPLICATION_SCOPE_BYTES
I will add these to the release notes.

> Project: HBase
> Issue Type: Improvement
> Components: shell
> Affects Versions: 2.0.0
> Reporter: Xiaolin Ha
> Assignee: Elliot Miller
> Priority: Minor
> Attachments: HBASE-20819.branch-2.001.patch,
> HBASE-20819.branch-2.002.patch,
> HBaseConstants-b5563432922268c7a16deacbb51bfba89c0a2aba.txt,

>
> HTableDescriptor is deprecated as of release 2.0.0, and will be removed in
> 3.0.0. This patch replaces all usages of HTableDescriptor and
> HColumnDescriptor in the hbase-shell module so that HTableDescriptor can be
> removed.
> There a few other consequences of this change:
> * Ruby methods relating to HTableDescriptor and HColumnDescriptor have been
> removed. This is noted in "Release Note" on this issue.
> * We no longer import constants from HTableDescriptor and HColumnDescriptor
> into the ruby HBaseConstants module. Instead, we import them from
> ColumnFamilyDescriptorBuilder and TableDescriptorBuilder.
