> Reporter: Sean Hsuan-Yi Chu

> First of all, this issue can be reproduced when drill runs on distributed
> mode.
> We have two json files in distributed file system. The type for the column is
> MAP and there is not schema change on the top level. However, in the one
> layer deeper in this column, the first file has one NullableBit column, which
> does not appear in the second file.
> The issue can be reproduced by the files in the attachment and this query :
> {code}
> select jsonFieldMapLevel1_aaa from directory
> {code}
