------------------------------
Summary: Error in performing operations on array casted as string
Key: DRILL-1462
URL: https://issues.apache.org/jira/browse/DRILL-1462
Project: Apache Drill
Issue Type: Bug
Affects Versions: 0.5.0
Environment: The following query casts an array as string to find out
the potential occurrence of Restaurant string in it. It is throwing an
exception.
0: jdbc:drill:zk=local> select cast (b.categories as varchar(250)) as
strCategories from
dfs.`/users/nrentachintala/Downloads/yelp_dataset_challenge_academic_dataset/yelp_academic_dataset_business.json`
b where strCategories LIKE 'Restaurants';
Error: exception while executing query: DrillBuf(ridx: 0, widx: 0, cap: 0/0,
unwrapped: DrillBuf(ridx: 0, widx: 0, cap: 0/0, unwrapped:
EmptyByteBufLE)).slice(0, 4) (state=,code=0)
If I rewrite the query as below, it fails as well. The specific failure cause
is unknown, but logging a bug as tracking.

b ) where strCategories LIKE '%Restaurants%';
