The Java > interface says that the value is undefined and in Linux/Sun it gets the 4096 > for the inode. Clearly this isn't useful. > It also recursively calls itself. In case the directory has a symbolic link > forming a cycle, getDU keeps spinning in the cycle. In our case, we saw this > in the org.apache.hadoop.mapred.JobLocalizer.downloadPrivateCacheObjects > call. This prevented other tasks on the same node from committing, causing > the TT to become effectively useless (because the JT thinks it already has > enough tasks running) -- This message is automatically generated by JIRA.
