Brahma Reddy Battula commented on HDFS-12781:
---------------------------------------------
[~Harsha1206] thanks for reporting.
As per [datable doc|https://datatables.net/manual/tech-notes/4], Each cell in
DataTables requests data, and when DataTables tries to obtain data for a cell
and is unable to do so, it will trigger a warning, telling you that data is not
available where it was expected to be.
when node is dead,as we can't get the values() it through's this warn.
When I give {{defaultContent}},this error will disappear.I feel, we should add
{{defaultContent}} to all the cells.
{code}
{ 'orderDataType': 'ng-value', 'searchable': true , "defaultContent":
"" },
{ 'orderDataType': 'ng-value', 'searchable': true ,
"defaultContent": ""},
{ 'orderDataType': 'ng-value', 'type': 'num' , "defaultContent":
0},
{ 'orderDataType': 'ng-value', 'type': 'num' , "defaultContent":
0},
{ 'orderDataType': 'ng-value', 'type': 'num' , "defaultContent":
0},
{ 'type': 'num' , "defaultContent": 0},
{ 'orderDataType': 'ng-value', 'type': 'num' , "defaultContent":
0},
{ 'type': 'string' , "defaultContent": ""}
