Jian Yi commented on HBASE-17182:
---------------------------------
This error is because the scanner was removed, getScanner(scannerId) get
scanner failed and throw TIllegalArgument("Invalid scanner Id").
scanPeriod is too small? Maybe getScannerRows costs too much time more than
scanPeriod. So testLongLivedScan need a larger scanPeriod.
> Memory leak from openScanner of HBase thrift2
