Field Details

serverName

private final ServerName serverName

remoteProcedures

private final Set<RemoteProcedureDispatcher.RemoteProcedure> remoteProcedures

numberOfAttemptsSoFar

private int numberOfAttemptsSoFar

maxWaitTime

private long maxWaitTime

rsRpcRetryInterval

private final long rsRpcRetryInterval

RS_RPC_RETRY_INTERVAL_CONF_KEY

private static final String RS_RPC_RETRY_INTERVAL_CONF_KEY

See Also:

• Constant Field Values

DEFAULT_RS_RPC_RETRY_INTERVAL

private static final int DEFAULT_RS_RPC_RETRY_INTERVAL

See Also:

• Constant Field Values

RS_REMOTE_PROC_FAIL_FAST_LIMIT

private static final String RS_REMOTE_PROC_FAIL_FAST_LIMIT

Config to determine the retry limit while executing remote regionserver procedure. This retry limit applies to only specific errors. These errors could potentially get the remote procedure stuck for several minutes unless the retry limit is applied.

See Also:

• Constant Field Values

DEFAULT_RS_REMOTE_PROC_RETRY_LIMIT

private static final int DEFAULT_RS_REMOTE_PROC_RETRY_LIMIT

The default retry limit. Waiting for more than 5 attempts is not going to help much for genuine connectivity errors. Therefore, consider fail-fast after 5 retries. Value = 5

• Constant Field Values

failFastRetryLimit

private final int failFastRetryLimit

request

private org.apache.hadoop.hbase.shaded.protobuf.generated.AdminProtos.ExecuteProceduresRequest.Builder request

 Set<RemoteProcedureDispatcher.RemoteProcedure> remoteProcedures)

Method Details

getRsAdmin

private AsyncRegionServerAdmin getRsAdmin()
                                   throws IOException

Throws:

IOException

getServerName

protected final ServerName getServerName()

scheduleForRetry

private boolean scheduleForRetry(IOException e)

unableToConnectToServer

private boolean unableToConnectToServer(IOException e)

The category of exceptions where we can ensure that the request has not yet been received and/or processed by the target regionserver yet and hence we can determine whether it is safe to choose different regionserver as the target.

Parameters:

e - IOException thrown by the underlying rpc framework.

Returns:

true if the exception belongs to the category where the regionserver has not yet received the request yet.

isSaslError

private boolean isSaslError(IOException e)

isConnectionClosedError

private boolean isConnectionClosedError(IOException e)

Returns true if the error or its cause is of type ConnectionClosedException.

Parameters:

e - IOException thrown by the underlying rpc framework.

Returns:

True if the error or its cause is of type ConnectionClosedException.

isErrorTypeFailFast

private boolean isErrorTypeFailFast(IOException e)

Returns true if the error type can allow fail-fast.

Parameters:

e - IOException thrown by the underlying rpc framework.

Returns:

True if the error type can allow fail-fast.

getMaxWaitTime

private long getMaxWaitTime()

unwrapException

private IOException unwrapException(IOException e)
