HbckReport

public HbckReport()

Method Details

getCheckingStartTimestamp

public Instant getCheckingStartTimestamp()

Used for web ui to show when the HBCK checking started.

setCheckingStartTimestamp

public void setCheckingStartTimestamp(Instant checkingStartTimestamp)

getCheckingEndTimestamp

public Instant getCheckingEndTimestamp()

Used for web ui to show when the HBCK checking report generated.

setCheckingEndTimestamp

public void setCheckingEndTimestamp(Instant checkingEndTimestamp)

getRegionInfoMap

public Map<String,HbckRegionInfo> getRegionInfoMap()

This map contains the state of all hbck items. It maps from encoded region name to HbckRegionInfo structure. The information contained in HbckRegionInfo is used to detect and correct consistency (hdfs/meta/deployment) problems.

getDisabledTableRegions

public Set<String> getDisabledTableRegions()

getSplitParentRegions

public Set<String> getSplitParentRegions()

getOrphanRegionsOnRS

public Map<String,ServerName> getOrphanRegionsOnRS()

The regions only opened on RegionServers, but no region info in meta.

getOrphanRegionsOnFS

public Map<String,org.apache.hadoop.fs.Path> getOrphanRegionsOnFS()

The regions have directory on FileSystem, but no region info in meta.

getInconsistentRegions

public Map<String,Pair<ServerName,List<ServerName>>> getInconsistentRegions()

The inconsistent regions. There are three case: case 1. Master thought this region opened, but no regionserver reported it. case 2. Master thought this region opened on Server1, but regionserver reported Server2 case 3. More than one regionservers reported opened this region
