Exception Summary | |
---|---|
CallSequenceOutOfOrderException | Thrown by a region server while doing scan related next() calls. |

DroppedSnapshotException | Thrown during flush if the possibility snapshot content was not properly persisted into store files. |
HBaseIOException | All hbase specific IOExceptions should be subclasses of HBaseIOException |
InvalidFamilyOperationException | Thrown if a request is table schema modification is requested but made for an invalid family name. |
MasterNotRunningException | Thrown if the master is not running |
NotAllMetaRegionsOnlineException | Thrown when an operation requires the root and all meta regions to be online |
NotServingRegionException | Thrown by a region server if it is sent a request for a region it is not serving. |
