Examples with ShellExecService org.apache.hadoop.hbase.coprocessor.protobuf.generated.ShellExecEndpoint.ShellExecService used on opensource projects

Example 1 with ShellExecService

use of org.apache.hadoop.hbase.coprocessor.protobuf.generated.ShellExecEndpoint.ShellExecService in project hbase by apache.

the class TestShellExecEndpointCoprocessor method testShellExecForeground.

private void testShellExecForeground(final Consumer<ShellExecRequest.Builder> consumer) {
    final AsyncConnection conn = connectionRule.getConnection();
    final AsyncAdmin admin = conn.getAdmin();
    final String command = "echo -n \"hello world\"";
    final ShellExecRequest.Builder builder = ShellExecRequest.newBuilder().setCommand(command);
    consumer.accept(builder);
    final ShellExecResponse resp = admin.<ShellExecService.Stub, ShellExecResponse>coprocessorService(ShellExecService::newStub, (stub, controller, callback) -> stub.shellExec(controller, builder.build(), callback)).join();
    assertEquals(0, resp.getExitCode());
    assertEquals("hello world", resp.getStdout());
}

Example 2 with ShellExecService

use of org.apache.hadoop.hbase.coprocessor.protobuf.generated.ShellExecEndpoint.ShellExecService in project hbase by apache.

the class TestShellExecEndpointCoprocessor method testShellExecBackground.

@Test
public void testShellExecBackground() throws IOException {
    final AsyncConnection conn = connectionRule.getConnection();
    final AsyncAdmin admin = conn.getAdmin();
    final File testDataDir = ensureTestDataDirExists(miniClusterRule.getTestingUtility());
    final File testFile = new File(testDataDir, "shell_exec_background.txt");
    assertTrue(testFile.createNewFile());
    assertEquals(0, testFile.length());
    final String command = "echo \"hello world\" >> " + testFile.getAbsolutePath();
    final ShellExecRequest req = ShellExecRequest.newBuilder().setCommand(command).setAwaitResponse(false).build();
    final ShellExecResponse resp = admin.<ShellExecService.Stub, ShellExecResponse>coprocessorService(ShellExecService::newStub, (stub, controller, callback) -> stub.shellExec(controller, req, callback)).join();
    assertFalse("the response from a background task should have no exit code", resp.hasExitCode());
    assertFalse("the response from a background task should have no stdout", resp.hasStdout());
    assertFalse("the response from a background task should have no stderr", resp.hasStderr());
    Waiter.waitFor(conn.getConfiguration(), 5_000, () -> testFile.length() > 0);
    final String content = new String(Files.readAllBytes(testFile.toPath())).trim();
    assertEquals("hello world", content);
