枚举 RegionMergeTransaction.RegionMergeTransactionPhase

java.lang.Object

java.lang.Enum<RegionMergeTransaction.RegionMergeTransactionPhase>

org.apache.hadoop.hbase.regionserver.RegionMergeTransaction.RegionMergeTransactionPhase

所有已实现的接口:

Serializable, Comparable<RegionMergeTransaction.RegionMergeTransactionPhase>

封闭接口:

RegionMergeTransaction

public static enum RegionMergeTransaction.RegionMergeTransactionPhase
extends Enum<RegionMergeTransaction.RegionMergeTransactionPhase>

Each enum is a step in the merge transaction.

STARTED

public static final RegionMergeTransaction.RegionMergeTransactionPhase STARTED

PREPARED

public static final RegionMergeTransaction.RegionMergeTransactionPhase PREPARED

Prepared

SET_MERGING

public static final RegionMergeTransaction.RegionMergeTransactionPhase SET_MERGING

Set region as in transition, set it into MERGING state.

CREATED_MERGE_DIR

public static final RegionMergeTransaction.RegionMergeTransactionPhase CREATED_MERGE_DIR

We created the temporary merge data directory.

CLOSED_REGION_A

public static final RegionMergeTransaction.RegionMergeTransactionPhase CLOSED_REGION_A

Closed the merging region A.

OFFLINED_REGION_A

public static final RegionMergeTransaction.RegionMergeTransactionPhase OFFLINED_REGION_A

The merging region A has been taken out of the server's online regions list.

CLOSED_REGION_B

public static final RegionMergeTransaction.RegionMergeTransactionPhase CLOSED_REGION_B

Closed the merging region B.

OFFLINED_REGION_B

public static final RegionMergeTransaction.RegionMergeTransactionPhase OFFLINED_REGION_B

The merging region B has been taken out of the server's online regions list.

STARTED_MERGED_REGION_CREATION

public static final RegionMergeTransaction.RegionMergeTransactionPhase STARTED_MERGED_REGION_CREATION

Started in on creation of the merged region.

PONR

public static final RegionMergeTransaction.RegionMergeTransactionPhase PONR

Point of no return. If we got here, then transaction is not recoverable other than by crashing out the regionserver.

COMPLETED

public static final RegionMergeTransaction.RegionMergeTransactionPhase COMPLETED

Completed

方法详细资料

values

public static RegionMergeTransaction.RegionMergeTransactionPhase[] values()

按照声明该枚举类型的常量的顺序, 返回 包含这些常量的数组。该方法可用于迭代 常量, 如下所示:

for (RegionMergeTransaction.RegionMergeTransactionPhase c : RegionMergeTransaction.RegionMergeTransactionPhase.values())
    System.out.println(c);

返回:

按照声明该枚举类型的常量的顺序返回的包含这些常量的数组

valueOf

public static RegionMergeTransaction.RegionMergeTransactionPhase valueOf(String name)

返回带有指定名称的该类型的枚举常量。 字符串必须与用于声明该类型的枚举常量的 标识符完全匹配。(不允许有多余 的空格字符。)

参数:

name - 要返回的枚举常量的名称。

返回:

返回带有指定名称的枚举常量

抛出:

IllegalArgumentException - 如果该枚举类型没有带有指定名称的常量

NullPointerException - 如果参数为空值
