Table (in ORC) format showing as text file when running explain query?

[#1]

when I run any query with explain on my table A (Hive 0.13). Below is a snapshot of result after a simple select query.

STAGE DEPENDENCIES:
  Stage-1 is a root stage
  Stage-0 is a root stage

STAGE PLANS:
  Stage: Stage-1
    Map Reduce
      Map Operator Tree:
          TableScan
            alias: temp_segments
            Statistics: Num rows: ****** Data size: ******  Basic stats: COMPLETE Column stats: NONE
            Select Operator
              expressions: column1 (type: string)
              outputColumnNames: _col0
              Statistics: Num rows: ******  Data size: ******  Basic stats: COMPLETE Column stats: NONE
              File Output Operator
                compressed: true
                Statistics: Num rows: ******  Data size: ******  Basic stats: COMPLETE Column stats: NONE
                table:
                    input format: org.apache.hadoop.mapred.TextInputFormat
                    output format: org.apache.hadoop.hive.ql.io.HiveIgnoreKeyTextOutputFormat
                    serde: org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe

  Stage: Stage-0
    Fetch Operator
      limit: -1

The table is in ORC for sure (verified). But here it is showing that table is text file. Any idea why is this there?

Can you share the complete query and desc extended for the table.

The qurey was a simple select a column query based on age.

@Akshat Mathur Did you ever get this resolved? I'm facing the same issue.
