---------------------------------
Summary: Metadata cache has duplicate columnTypeInfo values
Key: DRILL-5018
URL: https://issues.apache.org/jira/browse/DRILL-5018
Project: Apache Drill
Issue Type: Bug
Components: Metadata
Affects Versions: 1.8.0
Reporter: Robert Hou
Assignee: Parth Chandra
This lineitem table has duplicate entries in its metadata file, although the
entries have slightly different values. This lineitem table uses
directory-based partitioning on year and month.
"columnTypeInfo" : {
"L_RETURNFLAG" : {
"name" : [ "L_RETURNFLAG" ],
"primitiveType" : "BINARY",
"originalType" : null,
"precision" : 0,
"scale" : 0,
"repetitionLevel" : 0,
"definitionLevel" : 1
},
"l_returnflag" : {
"name" : [ "l_returnflag" ],
"primitiveType" : "BINARY",
"originalType" : "UTF8",
"precision" : 0,
"scale" : 0,
"repetitionLevel" : 0,
"definitionLevel" : 0
},
This lineitem table has two entries in its metadata file for each column, but
the two entries have different column names (adding a zero). It also has
slightly different values. This lineitem table was created using CTAS with the
first table above.
"l_shipinstruct" : {
"name" : [ "l_shipinstruct" ],
"primitiveType" : "BINARY",
"originalType" : "UTF8",
"precision" : 0,
"scale" : 0,
"repetitionLevel" : 0,
"definitionLevel" : 0
},
"L_SHIPINSTRUCT0" : {
"name" : [ "L_SHIPINSTRUCT0" ],
"primitiveType" : "BINARY",
"originalType" : null,
"precision" : 0,
"scale" : 0,
"repetitionLevel" : 0,
"definitionLevel" : 1
},
