Description

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 #:

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

• Try to access it via Knox 0.9.0 and above:

# curl -iku user:pass -X GET 'https://srv-knx01:8443/gateway/default/hbase/hbaseexample/5%23'
HTTP/1.1 404 Not Found

Not found

• No issues with Knox 0.8.0 and below:

# curl -iku user:pass -X GET 'https://srv-knx01:8443/gateway/default/hbase/hbaseexample/5%23'

Thank you in advance.
