Description

I'm using datastage to create file in Hadoop through webhdfs.

It happens that when namenode failover happens, datastage is sometimes talking to the standby namenode.

Then create operation succeed but when files are bigger than the buffer size, datastage calls the APPEND operation and get back a 403 response.

It seems not very coherent that some write operation are allowed on the stand-by and other aren't.

 

Regards,
