Example 3 with KeyValue

use of org.apache.hadoop.hdds.protocol.datanode.proto.ContainerProtos.KeyValue in project ozone by apache.

the class ContainerProtocolCalls method writeSmallFile.

/**

 * name, block name and data to write sends all that data to the container
 * using a single RPC. This API is designed to be used for files which are
 * smaller than 1 MB.
