Description

 } catch (IOException e) {
          LOG.error("Shuffle error :", e);

In cases where the read from a disk fails and throws a DiskErrorException, the shuffle handler prints the entire stack trace for each and every one of the failures causing the nodemanager logs to quickly fill up the disk.
