> I am trying to create a table in hbase through knox gateway ( 0.6.0) using following command:
>
> curl -v -ik -u guest:guest-password -H "Accept: text/xml" -H "Content-Type: text/xml" -d '<?xml version="1.0" encoding="UTF-8"?><TableSchema name="table1"><ColumnSchema name="family1"/><ColumnSchema name="family2"/></TableSchema>' -X PUT 'https://localhost:8443/gateway/sandbox/hbase/table1/schema'
>
> Always 2 tables was created successfully but when I try to create third table its hang and restart of knox gateway service is required.
> This scenario occur during creation of table and also putting data into tables in hbase.
> same scenario is working fine with older knox version 0.5.1
>
>
> output of curl ( when hang occur)

> I think gateway tries to establish connection with Hadoop service but number of route allocation reach to max limit “route allocated: 2 of 2 “so its hang. So may be after previous hbase creation table curl commands knox did not released there connection.
