Summary: "SELECT * BadAlias ..." yields "SYSTEM ERROR ... index (-1) must not be negative" Key: DRILL-2956 URL: https://issues.apache.org/jira/browse/DRILL-2956 Project: Apache Drill Issue Type: Bug Reporter: Daniel Barclay (Drill) Issuing the query: select * alias from `dfs.tmp`.`empty_file.json` ; (where /tmp/empty_file.json exists and is completely empty) yields an internal error: > select * alias from `dfs.tmp`.`empty_file.json` ; Error: SYSTEM ERROR: Unexpected exception during fragment initialization: index (-1) must not be negative [Error Id: 633d45db-5d05-4b15-84ee-88eaf11e9ba2 on dev-linux2:31010] (state=,code=0) > It doesn't seem to matter whether the input file is empty or contains some JSON. (Using a table from INFORMATION_SCHEMA (a schema whose tables and columns are known statically) does not yield the same error: > select * alias from INFORMATION_SCHEMA.CATALOGS; May 04, 2015 11:49:01 PM org.apache.calcite.sql.validate.SqlValidatorException <init> SEVERE: org.apache.calcite.sql.validate.SqlValidatorException: Unknown identifier '*' May 04, 2015 11:49:01 PM org.apache.calcite.runtime.CalciteException <init> SEVERE: org.apache.calcite.runtime.CalciteContextException: At line 1, column 8: Unknown identifier '*' Error: PARSE ERROR: At line 1, column 8: Unknown identifier '*' [Error Id: 1504c5cd-9c60-44ec-b4f2-dad837329bff on dev-linux2:31010] (state=,code=0) > However, that error doesn't seem right either. (I would think that trying to give an alias name after "*" would be a syntax error (rather than a name lookup error).)) -- This message was sent by Atlassian JIRA (v6.3.4#6332)
