1.我的 namenode 日志总是打印错误日志 java.io.IOException: Requested data length 113675682 is longer than maximum configured RPC length 67108864. RPC came from 172.16.. 以及 datanode 印刷品 Unsuccessfully sent block report 0x706cd6d00df0effe, containing 1 storage report(s), of which we sent 0. The reports had 9016550 total blocks and used 0 RPC(s). This took 1734 msec to generate and 252 msecs for RPC and NN processing. Got back no commands 2.我设置 ipc.maximum.data.length 到134217728解决了问题，但不幸的是，我发现设置长度后，我的 hdfs 客户机通常无法写入数据，但每次只需几分钟 namenode 当客户端无法写入时抛出新异常， DatanodeProtocol.blockReport from 172.16..:43410 Call#30074227 Retry#0 java.lang.IllegalStateException: com.google.protobuf.InvalidProtocolBufferException: Protocol message was too large. May be malicious. Use CodedInputStream.setSizeLimit() to increase the size limit. 就像参考hdfs-5153一样，它说namesystem写锁在这段时间内保持`
我必须破解protobuf jar并设置限制？
