This property specifies whether to connect to the HDFS when the connection is opened.

Data Type

bool

Default Value

false

Remarks

When set to true, a connection will be made to HDFS when the connection is opened. This property enables the Test Connection feature available in various database tools.

This feature acts as a NOOP command as it is used to verify a connection can be made to HDFS and nothing from this initial connection is maintained.

Setting this property to false may provide performance improvements (depending upon the number of times a connection is opened).
