Example 1 with UfsMode

use of alluxio.underfs.UfsMode in project alluxio by Alluxio.

the class DefaultFileSystemMaster method checkUfsMode.

/**
 * Check if the specified operation type is allowed to the ufs.
 *
 * @param alluxioPath the Alluxio path

 */
private void checkUfsMode(AlluxioURI alluxioPath, OperationType opType) throws AccessControlException, InvalidPathException {
    MountTable.Resolution resolution = mMountTable.resolve(alluxioPath);
    try (CloseableResource<UnderFileSystem> ufsResource = resolution.acquireUfsResource()) {
        UnderFileSystem ufs = ufsResource.get();
        UfsMode ufsMode = ufs.getOperationMode(mUfsManager.getPhysicalUfsState(ufs.getPhysicalStores()));
