任务失败，在java.lang.ArrayIndexOutOfBoundsException处显示com.ning.compress.lzf.impl.UnsafeChunkDecoder.copyOverlappingLong。
重复的任务失败后，整个工作被终止。
几天前它运行没有问题。
目前，我们怀疑该群集正在发生故障，因为从昨天开始，Ambari(Hortonworks Hadoop群集管理器)报告了损坏的块，节点问题等。
即使完全重新安装了群集，该问题仍然存在。 (我们的集群很小-只有3个数据节点)因此，这可能是硬件问题。
可能是网络问题吗？还是磁盘？
详细日志如下:

最佳答案
当我更换可疑数据节点并重新安装群集时，问题就消失了。
我怀疑该数据节点的磁盘发生故障，因此从该磁盘读取的数据已损坏，并且解码器无法处理无效的输入数据。
