Andrew Purtell commented on HBASE-10112:
----------------------------------------

Sure J-M I will commit to all branches once [~stack] acks for 0.96. (Stack - in the future I could exercise appropriate judgement in cases like this, just say.)

> 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. Reason:
> <pre>    String index out of range: 50</pre></p><h3>Caused by:</h3><pre>java.lang.StringIndexOutOfBoundsException: String index out of range: 50
>     at java.lang.AbstractStringBuilder.charAt(AbstractStringBuilder.java:174)
>     at java.lang.StringBuilder.charAt(StringBuilder.java:55)
>     at org.apache.hadoop.hbase.rest.RowSpec.parseQueryParams(RowSpec.java:260)
>     at org.apache.hadoop.hbase.rest.RowSpec.&lt;init&gt;(RowSpec.java:59)
>     at 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 (never tried to build hbase myself).
