[jira] [Updated] (PARQUET-1956) "parquet-tools cat -j" should not output metadata

     [ https://issues.apache.org/jira/browse/PARQUET-1956?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Dumitru Husleag updated PARQUET-1956:
-------------------------------------
    Description: 
Parquet-tools cat -help says:

{noformat}
parquet-tools cat:
Prints the content of a Parquet file. The output contains only the data, no
metadata is displayed
{noformat}


Let's say I have a structure like this in a Parquet file:
{code:json}
{
   "account": 
   [
		{
			"accountDepositType": "NA",
			"accountNumber": "NA",
			"accountHolderType": "NA"
		}
	]
}
{code}

it is extracted like this

{code:json}
{
   "account": {
		"list": [
			{
				"element": {
					"accountDepositType": "NA",
					"accountNumber": "NA",
					"accountHolderType": "NA"
				}
			}
		]
	}
}
{code}

*"list"* and *"element"* is metadata or type information if you like and it should not appear in output.

Can you please fix that ?
