/**
 * <p>Stops an DataSync task execution that's in progress. The transfer of some
 *       files are abruptly interrupted. File contents that're transferred to the destination might be
 *       incomplete or inconsistent with the source files.</p>
 *          <p>However, if you start a new task execution using the same task and allow it to finish,
 *       file content on the destination will be complete and consistent. This applies to other
 *       unexpected failures that interrupt a task execution. In all of these cases, DataSync
 *       successfully completes the transfer when you start the next task execution.</p>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { DataSyncClient, CancelTaskExecutionCommand } from "@aws-sdk/client-datasync"; // ES Modules import
 * // const { DataSyncClient, CancelTaskExecutionCommand } = require("@aws-sdk/client-datasync"); // CommonJS import
 * // import type { DataSyncClientConfig } from "@aws-sdk/client-datasync";
 * const config = {}; // type is DataSyncClientConfig
 * const client = new DataSyncClient(config);
 * const input = { // CancelTaskExecutionRequest
 *   TaskExecutionArn: "STRING_VALUE", // required
 * };
 * const command = new CancelTaskExecutionCommand(input);
 * const response = await client.send(command);
 * // {};
 *
 * ```
 *
 * @param CancelTaskExecutionCommandInput - {@link CancelTaskExecutionCommandInput}
 * @returns {@link CancelTaskExecutionCommandOutput}
 * @see {@link CancelTaskExecutionCommandInput} for command's `input` shape.
 * @see {@link CancelTaskExecutionCommandOutput} for command's `response` shape.
 * @see {@link DataSyncClientResolvedConfig | config} for DataSyncClient's `config` shape.
 *
 * @throws {@link InternalException} (server fault)
 *  <p>This exception is thrown when an error occurs in the DataSync
 *       service.</p>
 *
 * @throws {@link InvalidRequestException} (client fault)
 *  <p>This exception is thrown when the client submits a malformed request.</p>
 *
 * @throws {@link DataSyncServiceException}
 * <p>Base exception class for all service exceptions from DataSync service.</p>
