Andrew Kyle Purtell commented on HBASE-28864:
---------------------------------------------
Locally, we are using the same versions as branch-2 for jruby (9.4.8.0), joni
(2.2.1), and jcodings (1.0.58).
I diffed our local hbase-shell module compared to upstream branch-2 and these
are the only differences:
- We are compiling with the Hadoop 3 profile
- Building against Hadoop 3.3.6
- An unrelated change in admin.rb where we do not have the
setErasureCodingPolicy support (because it's based on branch-2.5)
- These commands are not included because they aren't supported in 2.5 so we
don't want to backport them, also unrelated, as they are not touching
irb/hirb.rb
-- list_enabled_tables
-- list_disabled_tables
-- truncate_region
-- peer_modification_enabled
-- peer_modification_switch
The rest of the code is the same. I can see no explanation why the local change
is needed, but if I do not define assignment_expression in our hirb.rb, then
this happens:
{noformat}
Took 0.0008 seconds
hbase:001:0> list
TABLE
0 row(s)
Took 0.4398 seconds
Traceback (most recent call last):
NoMethodError (undefined method `assignment_expression?' for
#<IRB::HIRB:0x2cea921a>)
{noformat}
and any other shell command experiences the same.

> After HBASE-28250 Bump jruby to 9.4.8.0 to fix snakeyaml CVE after every
> command the message "NoMethodError undefined method assignment_expression?"
> is printed.
> This is called from code copied from
> https://github.com/ruby/irb/blob/v1.4.2/lib/irb.rb . The fix is to also copy
