Sandeep More commented on KNOX-1005:
------------------------------------
Hello [~lmccay], thanks for pointing it out, I had not tested it with KNOX-709.
After testing it, it does look like there is an issue, specifically with the
"," character.
{code}

But, this is not caused by Knox, you get the same issue when a direct request
is made to WebHbase. I do not think this should be fixed in Knox and definitely
not by blindly encoding everything, it would create more problems than it would
solve. Let me know your thoughts on it !

> Key: KNOX-1005
> URL: https://issues.apache.org/jira/browse/KNOX-1005
> Project: Apache Knox
> Issue Type: Bug
> Components: Server
> Affects Versions: 0.9.0, 0.9.1, 0.10.0, 0.11.0, 0.12.0, 0.13.0
> Environment: CentOS Linux release 7.3.1611, HBase 1.1.2
> Reporter: Roman
> Assignee: Sandeep More
> Labels: regresion
> Fix For: 0.14.0
>
> Attachments: KNOX-1029.001.patch
>
>
> Hello,
> Any HBase row containing special characters in the name (for example #)
> throws 404 Not Found error if accessed via Knox 0.9.0 and above. Accessing
> the same row directly via HBase Rest works without any issues.
> I haven't tried with other special characters though, and I think this is
> caused by KNOX-709.
> How to reproduce:
> - Create an entry in HBase containing #:
> {code:java}
> hbase(main):002:0> put 'hbaseexample', '5#', 'columns:_c1', 'test'
> hbase(main):002:0> scan 'hbaseexample'
> ROW COLUMN+CELL
> 5# column=columns:_c1, timestamp=1503660672170, value=test
> 1 row(s) in 0.6700 seconds{code}
> - Try to access it via Knox 0.9.0 and above:
> {code:java}
> # curl -iku user:pass -X GET
> 'https://srv-knx01:8443/gateway/default/hbase/hbaseexample/5%23'
> HTTP/1.1 404 Not Found
