Catalog Server Out of memory when upgrading from CDH 5.5 -> 5.7

[廖松博]

Hi all,

         I see the issue https://issues.cloudera.org/browse/IMPALA-3910 , it 
says “No one table is large enough to breach the 2GB array size limit (as 
described in IMPALA-2648) but multi table updates may.”
         Is that true ? If yes,  a concurrent DDL should be avoid , otherwise 
it may cause a OOM, right ?
         Thanks.
