httpclient5 with connection pooling in java

I am trying to use httpclient5 with connection pooling. Below are some of the points mentioned in documentation:

CloseableHttpClient instances should be closed when no longer needed or about to go out of score.

IMPORTANT: Always re-use CloseableHttpClient instances. They are expensive to create, but they are also fully thread safe, so multiple threads can use the same instance of CloseableHttpClient to execute multiple requests concurrently taking full advantage of persistent connection re-use and connection pooling.

I feel both of them feels contradictory. How should I proceed with this? Also in case if I am reusing CloseableHttpClient instances how can I change credentials for different requests which uses same client?

depends on your auth type... for e.g. basic auth just set the header manually for each request

final HttpGet request = new HttpGet(URL_SECURED_BY_BASIC_AUTHENTICATION);
final String auth = DEFAULT_USER + ":" + DEFAULT_PASS;
final byte[] encodedAuth = Base64.encodeBase64(auth.getBytes(StandardCharsets.ISO_8859_1));
final String authHeader = "Basic " + new String(encodedAuth);
request.setHeader(HttpHeaders.AUTHORIZATION, authHeader);
