示例1: initDelegationToken
import org.apache.hadoop.hdfs.security.token.delegation.DelegationTokenSelector; //导入依赖的package包/类
protected void initDelegationToken() throws IOException {
// look for webhdfs token, then try hdfs
final Text serviceName = SecurityUtil.buildTokenService(nnAddr);
Token<?> token = DT_SELECTOR.selectToken(serviceName, ugi.getTokens());
if (token == null) {
token = DelegationTokenSelector.selectHdfsDelegationToken(
nnAddr, ugi, getConf());
}
//since we don't already have a token, go get one
boolean createdToken = false;
if (token == null) {
token = getDelegationToken(null);
createdToken = (token != null);
}
// security might be disabled
if (token != null) {
setDelegationToken(token);
if (createdToken) {
addRenewAction(this);
LOG.debug("Created new DT for " + token.getService());
} else {
LOG.debug("Found existing DT for " + token.getService());
}
}
}
示例2: selectHdfsDelegationToken
import org.apache.hadoop.hdfs.security.token.delegation.DelegationTokenSelector; //导入依赖的package包/类
