Maximum Java heap size for HBase Region Servers (Java option -Xmx)

+ +

Important: For more information on sizing, see Recommended Memory + Configurations for the MapReduce Service for recommended sizing.

+
+

HBase Region Server Handler

+ 		+

+ Count of RPC Listener instances spun up on RegionServers

+
HBase Region Major Compaction +

The time between major compactions of all HStoreFiles in a region. Set to 0 to disable + automated major compactions.

+
HBase Region Block MultiplierBlock updates if memstore reaches "Multiplier * HBase Region Memstore + Flush + Size" bytes. Useful preventing runaway memstore size during spikes in update + traffic +
HBase Region Memstore Flush Size +

Memstore will be flushed to disk if size of the memstore exceeds this number of bytes.

+

HBase HStore compaction threshold

+ 		+

When HStoreFiles in any one HStore are greater than this number, a compaction is run to rewrite all + HStoreFiles files as one.

+
+

HFile block cache size

+ 		+

Percentage of maximum heap (-Xmx setting) to allocate to block cache used by HFile/StoreFile. You can + set this to 0 to disable but this is not a recommended practice.

+
+

Maximum HStoreFile Size

+ 		+

If any one of a column families' HStoreFiles grows to exceed this value, the hosting HRegion + is split in two.

+
+

HBase Client Scanner Caching

+ 		+

Number of rows that will be fetched when calling next on a scanner if it + is not served from (local, client) memory. Do not set this value such that the time between invocations + is greater than the scanner timeout

+
+

Zookeeper timeout for HBase Session

+ 		+

HBase passes this to the zk quorum as suggested maximum time for a session.

+
+

HBase Client Maximum key-value Size

+ 		+

Specifies the combined maximum allowed size of a KeyValue instance. It should be set to a + fraction of the maximum region size.

+
+

hstore blocking storefilesIf more than this number of StoreFiles in any one Store (one StoreFile is written per flush + of MemStore), then updates are blocked in this HRegion until compaction is completed or until + hbase.hstore.blockingWaitTime is exceeded. +
hbase.master.lease.thread.wakefrequencyThe interval between checks for the expired region server leases. The default is 15 seconds + but may be reduced so that + the master notices a dead RegionServer more quickly. +
hbase.superuserComma-separated list of users who are allowed full privileges across the cluster, + regardless + of stored ACLs. Used only when HBase security is enabled. +
hbase.regionserver.optionalcacheflushintervalAmount of time to wait since the last time a region was flushed before invoking an optional + cache flush. Default is 60,000. +
Custom HBase ConfigsUse this text box to enter values for hbase-site.xml properties not exposed by the UI. + Enter + in "key=value" format, with a newline as a delimiter between pairs. +
