Ted Yu created HBASE-15132: ------------------------------ Summary: Master region merge RPC should authorize user request Key: HBASE-15132 URL: https://issues.apache.org/jira/browse/HBASE-15132 Project: HBase Issue Type: Bug Reporter: Ted Yu Assignee: Ted Yu
The normal flow for region merge is: 1. client sends a master RPC for dispatch merge regions 2. master moves the regions to the same regionserver 3. master calls mergeRegions RPC on the regionserver. For user initiated region merge, MasterRpcServices#dispatchMergingRegions() is called by HBaseAdmin. There is no coprocessor invocation in step 1. Step 3 is carried out in the "hbase" user context. This leaves potential security hole - any user without proper authorization can merge regions of any table. Thanks to Enis who spotted this flaw first. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
