Field Detail

extraCacheServerArgs

public static Long extraCacheServerArgs

(String[]) An array of Strings of the extraArgs to be passed in to the CacheServer VM when invoked via hydra.CacheServerHelper.startCacheServer()

verifyBalance

public static Long verifyBalance

(boolean) Whether or not to verify RebalanceResults (isBalanceImproved). Note that this can only be done when the rebalance task is done serially (or only assigned to one thread) and membership is not changing during rebalance. Defaults to false.

waitForNetworkDrop

public static Long waitForNetworkDrop

(boolean) Whether or not to to wait for networkDropComplete prior to returning from RebalanceTest.HydraTask_rebalance. Used by serialPRNetDown tests. Defaults to false.

resourceObserver

public static Long resourceObserver

(String) Class name of the InternalResourceManager.ResourceObserver to install on the cache. Used by rebalance tests. Defaults to null. This provides a test hook callback when rebalance or recovery is started/finished.

numRegions

public static Long numRegions

(int) numRegions (for multipleRegions and/or colocatedWith testing) Defaults to 1.

actionDelaySecs

public static Long actionDelaySecs

(int) actionDelaySecs (killTargetVm.conf will use this for killing the the rebalancer VM after processing the rebalancingStarted event. We need to delay a bit to let rebalancing get started though. Default value is 0.

targetEvent

public static Long targetEvent

(String) Which ResourceObserver event triggers a test action. For example, if we want to kill the rebalancer during a rebalance, the event will be rebalanceStarted. targetEvent is also used to time the 'cancel' operation. Valid values: rebalancingStarted, movingBucket, movingPrimary Also: skipSimulate (used to avoid extra ResourceObserver messages associated with simulate). See rebalance/hct_failover.conf Defaults to null.

numKeys

public static Long numKeys

(int) The number of keys to load.

useHashKey

public static Long useHashKey

(boolean) If true, then use HashKey to put to create uneven buckets.

hashKeyLimit

public static Long hashKeyLimit

(int) The limit of the number of hashCodes that can be used for HashKeys.

localMaxMemory

public static Long localMaxMemory

(int) The local max memory setting for the PR. Valid values:

rebalanceAction

public static Long rebalanceAction

(String) Action (cancel or kill) to perform at point targetEvent during Rebalance. Valid values: cancel, kill. Defaults to none.

actionRequired

public static Long actionRequired

(boolean) Whether data is required to move during rebalancing. true => if no data is moved/transferred, throw an Exception false => log a warning if no data moved/transferred during rebalance.
