Re: Impala Assignment locality concerning

I dont kow if you have a custom trigger or a built in trigger for health test. 

Is the health test showing warning or critical or bad ? 


either way the test is  to find the data locality in the host .

" Make sure that Impala Daemon is co-located with a DataNode, and that the IP address of each Impala Daemon matches the IP address of its co-located DataNode" 


Please make sure if  you have enabled the below properties in hdfs-site.xml
