Description

git.commit.id.abbrev=6676f2d

Data Set :

{
  "id" : 1,
  "map":{"rm": [
    {"mapid":"m1","mapvalue":{"col1":1,"col2":[0,1,2,3,4,5]},"rptd": [{ "a": "foo"},{"b":"boo"}]},
    {"mapid":"m2","mapvalue":{"col1":0,"col2":[]},"rptd": [{ "a": "bar"},{"c":1},{"d":4.5}]}
  ]}
}

The below CTAS statement fails though the underlying query succeeds

create table rep_map as select d.map from `temp.json` d;
Query failed: Query stopped., index: -4, length: 4 (expected: range(0, 16384)) [ d76e3f74-7e2c-406f-a7fd-5efc68227e75 on qa-node190.qa.lab:31010 ]

Error from the logs :

Caused by: java.lang.IndexOutOfBoundsException: index: -4, length: 4 (expected: range(0, 16384))
