hzxiongyinke opened a new pull request, #4651:
URL: https://github.com/apache/hive/pull/4651
… "Cannot connect to namenode"
### What changes were proposed in this pull request?
@Override
protected void analyzeCommand(TableName tableName, Map<String, String>
partitionSpec, ASTNode command)
throws SemanticException {
String newLocation = unescapeSQLString(command.getChild(0).getText());
try
{ // To make sure host/port pair is valid, the status of the location does
not matter FileSystem.get(new URI(newLocation), conf).getFileStatus(new
Path(newLocation)); }
catch (FileNotFoundException e)
{ // Only check host/port pair is valid, whether the file exist or not does
not matter }
catch (Exception e)
{ throw new SemanticException("Cannot connect to namenode, please check if
host/port pair for " + newLocation + " is valid", e); }
When the
"FileSystem.get(new URI(newLocation), conf).getFileStatus(new
Path(newLocation))"
code throws a "Permission denied" exception, the Beeline client will receive
the confusing exception "Cannot connect to namenode, please check if host/port
pair for". In reality, the issue is not with the namenode.
