> 1. Create MapR-DB binary table and put some data using HBase shell:
> {code:none}
> hbase shell
> create '/tmp/bintable','name','address'
> put '/tmp/bintable','100','name:first_name','john'
> put '/tmp/bintable','100','name:last_name','doe'
> put '/tmp/bintable','100','address:city','Newark'
> put '/tmp/bintable','100','address:state','nj'
> scan '/tmp/bintable'
> {code}
> 2. Drill config: ensure that dfs storage plugin has "connection": "maprfs:///" and contains format: 
> {code:java}
> "maprdb": {
> "type": "maprdb",
> "allTextMode": true,
> "enablePushdown": false,
> "disableCountOptimization": true
> }
> {code}
> 3. Check that table can be selected from Drill : 
> {code:java}
> select * from dfs.`/tmp/bintable`;
> {code}
> 4. Create Drill view 
> {code:java}
> create view dfs.tmp.`testview` as select * from dfs.`/tmp/bintable`;
> {code}
> 5. Query the view results into exception:
> {code:java}
> 0: jdbc:drill:> select * from dfs.tmp.`testview`;
> Error: SYSTEM ERROR: UnsupportedOperationException: Unable to convert cast expression CastExpression [input=`address`, type=minor_type: MAP
> mode: REQUIRED
> ] into string.
> Please, refer to logs for more information.
> [Error Id: 109acd00-7456-4a74-8a17-485f8999000f on node1.cluster.com:31010] (state=,code=0)
> {code}
> *UPDATE*
> This issue may be reproduced also when avro files with map columns are queried using Drill. Appropriate test was added to PR commit.
