Constructor Detail

Builder

public Builder()

Default constructor - use this builder to create a QueryState object.

Method Detail

withConfOverlay

public QueryState.Builder withConfOverlay(Map<String,String> confOverlay)

Set this if there are specific configuration values which should be added to the original config. If at least one value is set, then the configuration will be detached from the original one.

Parameters:

confOverlay - The query specific parameters

Returns:

The builder

nonIsolated

public QueryState.Builder nonIsolated()

Disable configuration isolation. For internal use / testing purposes only.

withGenerateNewQueryId

public QueryState.Builder withGenerateNewQueryId(boolean generateNewQueryId)

Set this to true if new queryId should be generated, otherwise the original one will be kept. If not set the default value is false.

Parameters:

generateNewQueryId - If new queryId should be generated

Returns:

The builder

withHiveConf

public QueryState.Builder withHiveConf(HiveConf hiveConf)

The source HiveConf object used to create the QueryState. If runAsync is false, and the confOverLay is empty then we will reuse the conf object as a backing datastore for the QueryState. We will create a clone of the conf object otherwise.

Parameters:

hiveConf - The source HiveConf

Returns:

The builder

withLineageState

public QueryState.Builder withLineageState(LineageState lineageState)

add a LineageState that will be set in the built QueryState

Parameters:

lineageState - the source lineageState

Returns:

the builder

build

public QueryState build()

Creates the QueryState object. The default values are: - runAsync false - confOverlay null - generateNewQueryId false - conf null

Returns:

The generated QueryState object
