Arina Ielchiieva updated DRILL-7138:
------------------------------------
Description:
As part of schema provisioning project, it will be handy for the user to see if
table has schema and its content.
Command syntax:
*describe schema for table dfs.tmp.`text_table`*
By default schema will be output in JSON format (format schema is stored in
.drill.schema file):
{noformat}
{
"table" : "dfs.tmp.`text_table`",
"schema" : {
"columns" : [
{
"name" : "id",
"type" : "INT",
"mode" : "OPTIONAL"
}
]
},
"version" : 1
}
{noformat}
JSON format can be indicated explicitly:
*describe schema for table dfs.tmp.`text_table` JSON*
Other formats:
STATEMENT - schema will be output in the form of CREATE SCHEMA statement.
