Subject hbase rest query params for maxVersions and maxValues
Date Sat, 07 Dec 2013 18:01:04 GMT
i am trying to use maxValues with a "globbed" row resource in stargate.
from looking at the source code one has to do something like

table/row/column(s)/timestamp(s)/?n=1

(except the ?n=1 piece must be urlencoded)

however i cannot get the n=1 piece to work. i get this stacktrace:

<p>Problem accessing
/some_table_name/93%2B002%2B*/cf:tx_CUST_NAME/1,13862892906600/%3Fn%3D1.

org.apache.hadoop.hbase.rest.RowResource.&lt;init&gt;(RowResource.java:74)
    at
org.apache.hadoop.hbase.rest.TableResource.getRowResource(TableResource.java:90)

the offending line is (260 in RowSpec):
c = query.charAt(i);

i think this should be
c = query.charAt(j);

same for line 248 (which handles the maxVersions)

i have not been able to test this.
