Interface AsyncAdminBuilder

All Known Implementing Classes:

AsyncAdminBuilderBase

@Public
public interface AsyncAdminBuilder

For creating AsyncAdmin. The implementation should have default configurations set before returning the builder to user. So users are free to only set the configs they care about to create a new AsyncAdmin instance.

Since:

2.0.0

Method Summary

Modifier and Type	Method	Description
AsyncAdmin	build()	Create a AsyncAdmin instance.
AsyncAdminBuilder	setMaxAttempts(int maxAttempts)	Set the max attempt times for an admin operation.
default AsyncAdminBuilder	setMaxRetries(int maxRetries)	Set the max retry times for an admin operation.
AsyncAdminBuilder	setOperationTimeout(long timeout, TimeUnit unit)	Set timeout for a whole admin operation.
AsyncAdminBuilder	setRetryPause(long timeout, TimeUnit unit)	Set the base pause time for retrying.
default AsyncAdminBuilder	setRetryPauseForCQTBE(long pause, TimeUnit unit)	Deprecated. Since 2.5.0, will be removed in 4.0.0.
AsyncAdminBuilder	setRetryPauseForServerOverloaded(long pause, TimeUnit unit)	Set the base pause time for retrying when HBaseServerException.isServerOverloaded().
AsyncAdminBuilder	setRpcTimeout(long timeout, TimeUnit unit)	Set timeout for each rpc request.
AsyncAdminBuilder	setStartLogErrorsCnt(int startLogErrorsCnt)	Set the number of retries that are allowed before we start to log.

Method Details

setOperationTimeout

AsyncAdminBuilder setOperationTimeout(long timeout,
 TimeUnit unit)

Set timeout for a whole admin operation. Operation timeout and max attempt times(or max retry times) are both limitations for retrying, we will stop retrying when we reach any of the limitations.

Returns:

this for invocation chaining

setRpcTimeout

AsyncAdminBuilder setRpcTimeout(long timeout,
 TimeUnit unit)

Set timeout for each rpc request.

Returns:

this for invocation chaining

setRetryPause

AsyncAdminBuilder setRetryPause(long timeout,
 TimeUnit unit)

Set the base pause time for retrying. We use an exponential policy to generate sleep time when retrying.

Returns:

this for invocation chaining

setRetryPauseForCQTBE

@Deprecated
default AsyncAdminBuilder setRetryPauseForCQTBE(long pause,
 TimeUnit unit)

Deprecated.

Since 2.5.0, will be removed in 4.0.0. Please use setRetryPauseForServerOverloaded(long, TimeUnit) instead.

Set the base pause time for retrying when HBaseServerException.isServerOverloaded(). We use an exponential policy to generate sleep time from this base when retrying.

This value should be greater than the normal pause value which could be set with the above setRetryPause(long, TimeUnit) method, as usually HBaseServerException.isServerOverloaded() means the server is overloaded. We just use the normal pause value for HBaseServerException.isServerOverloaded() if here you specify a smaller value.

• setRetryPause(long, TimeUnit)

setRetryPauseForServerOverloaded

AsyncAdminBuilder setRetryPauseForServerOverloaded(long pause,
 TimeUnit unit)

Set the base pause time for retrying when HBaseServerException.isServerOverloaded(). We use an exponential policy to generate sleep time when retrying.

This value should be greater than the normal pause value which could be set with the above setRetryPause(long, TimeUnit) method, as usually HBaseServerException.isServerOverloaded() means the server is overloaded. We just use the normal pause value for HBaseServerException.isServerOverloaded() if here you specify a smaller value.

setMaxRetries

default AsyncAdminBuilder setMaxRetries(int maxRetries)

Set the max retry times for an admin operation. Usually it is the max attempt times minus 1. Operation timeout and max attempt times(or max retry times) are both limitations for retrying, we will stop retrying when we reach any of the limitations.

Returns:

this for invocation chaining

setMaxAttempts

AsyncAdminBuilder setMaxAttempts(int maxAttempts)

Set the max attempt times for an admin operation. Usually it is the max retry times plus 1. Operation timeout and max attempt times(or max retry times) are both limitations for retrying, we will stop retrying when we reach any of the limitations.

Returns:

this for invocation chaining

setStartLogErrorsCnt

AsyncAdminBuilder setStartLogErrorsCnt(int startLogErrorsCnt)

Set the number of retries that are allowed before we start to log.

Returns:

this for invocation chaining

build

AsyncAdmin build()

Create a AsyncAdmin instance.

Returns:

a AsyncAdmin instance
