Hi, I am wondering if I run INVALIDATE METADATA for the whole database on node1 Then I ran a query on node2 – would the query on node2 used the cached metadata for the tables or it would know it’s invalidated?
And second how safe it is to run it for a database with many (say 30) tables over 10,000 partitions and 2000 more under 5000 partitions (most of the under 100) And each Impala Deamon node has a little (below Cloudera recommended) memory (32G) Thanks, Antoni
