-----------------------------------------
Assignee: Sanjana Malhotra
> Update the doc of Impala components
> -----------------------------------
>
> Key: IMPALA-13071
> URL: https://issues.apache.org/jira/browse/IMPALA-13071
> Project: IMPALA
> Issue Type: Documentation
> Reporter: Quanlong Huang
> Assignee: Sanjana Malhotra
> Priority: Major
>
> We need to update some discription in the doc of Impala components.
> [https://impala.apache.org/docs/build/asf-site-html/topics/impala_components.html]
> In the section ofThe Impala Catalog Service, this is stale:
> {quote}When you create a table, load data, and so on through Hive, you do
> need to issue REFRESH or INVALIDATE METADATA on an Impala daemon before
> executing a query there.
> {quote}
> We should mention "Automatic Invalidation/Refresh of Metadata", a.k.a. HMS
> event processor, and add links for it.
> Change "Impala daemons" to "Impala Coordinators" in this sentence:
> {quote}The Impala component known as the Catalog Service relays the metadata
> changes from Impala SQL statements to all the Impala
> {color:#de350b}daemons{color} in a cluster.
> {quote}
> Also add this link for "On-demand Metadata"
