Description

The WebHdfsHttpClientDispatch class is throwing a NullPointerException when used against a secure cluster

2014-10-22 16:15:27,789 ERROR hadoop.gateway (AbstractGatewayFilter.java:doFilter(69)) - Failed to execute filter: java.lang.NullPointerException
java.lang.NullPointerException
       at org.apache.hadoop.gateway.dispatch.HttpClientDispatch.executeKerberosDispatch(HttpClientDispatch.java:197)
       at org.apache.hadoop.gateway.dispatch.HttpClientDispatch.executeOutboundRequest(HttpClientDispatch.java:125)

this is because it isn't properly calling super.init in it's init method.
