Examples with RetryConfig org.apache.hadoop.hbase.util.RetryCounter.RetryConfig used on opensource projects

Example 1 with RetryConfig

use of org.apache.hadoop.hbase.util.RetryCounter.RetryConfig in project hbase by apache.

the class ProcedureUtil method createRetryCounter.

/**
 * Get a retry counter for getting the backoff time. We will use the
 * {@link ExponentialBackoffPolicyWithLimit} policy, and the base unit is 1 second, max sleep time
 * is 10 minutes by default.
 * <p/>
 * For UTs, you can set the {@link #PROCEDURE_RETRY_SLEEP_INTERVAL_MS} and
 * {@link #PROCEDURE_RETRY_MAX_SLEEP_TIME_MS} to make more frequent retry so your UT will not
 * timeout.

Example 2 with RetryConfig

use of org.apache.hadoop.hbase.util.RetryCounter.RetryConfig in project hbase by apache.
