Description

Overwrite of blocks fails, because "OverWriteRequested" flag is not set during chunk creation.

2017-05-16 22:33:23,909 [nioEventLoopGroup-5-2] ERROR      - Rejecting write chunk request. Chunk overwrite without explicit request. ChunkInfo{chunkName='1_chunk, offset=0, len=
11933}

This flag needs to be set here

public static void writeSmallFile(XceiverClientSpi client, String containerName,
      String key, byte[] data, String traceID) throws IOException {
.....
    ChunkInfo chunk = ChunkInfo
        .newBuilder()
        .setChunkName(key + "_chunk")
        .setOffset(0)
        .setLen(data.length)
        .build();
