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

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.
