示例1: mutateRows
import org.apache.hadoop.hbase.regionserver.WrongRegionException; //导入依赖的package包/类
@Override
public void mutateRows(List<Mutation> mutations) throws IOException {
// get the coprocessor environment
RegionCoprocessorEnvironment env = (RegionCoprocessorEnvironment) getEnvironment();
// set of rows to lock, sorted to avoid deadlocks
SortedSet<byte[]> rowsToLock = new TreeSet<byte[]>(Bytes.BYTES_COMPARATOR);
HRegionInfo regionInfo = env.getRegion().getRegionInfo();
for (Mutation m : mutations) {
// check whether rows are in range for this region
if (!HRegion.rowIsInRange(regionInfo, m.getRow())) {
String msg = "Requested row out of range '"
+ Bytes.toStringBinary(m.getRow()) + "'";
if (rowsToLock.isEmpty()) {
// if this is the first row, region might have moved,
// allow client to retry
throw new WrongRegionException(msg);
} else {
// rows are split between regions, do not retry
throw new DoNotRetryIOException(msg);
}
}
rowsToLock.add(m.getRow());
}
// call utility method on region
env.getRegion().mutateRowsWithLocks(mutations, rowsToLock);
